DIFFERENCES BETWEEN DOUBLE COLOR MOLD AND OVERMOLD

Double color mold: two kinds of plastic materials are molded on the same injection molding machine, and are molded in two times, but the products only die once. Generally, this molding process is also called double injection molding, usually by a set of molds, and a special two-color injection molding machine is needed.
Overmold: two kinds of plastic materials do not have to be injected into the same injection machine and are molded in two times. After taking out the mold from a set of moulds, the product is then placed in another set of moulds for second injection molding. Therefore, the general molding process is usually done by two sets of molds instead of a special two-color injection molding machine.
Double color mold and overmold overview: the design should pay attention to the positioning of overmold, need to make the adhesive sealing and the reverse slope on the rubber parts to prevent the deformation of the glue. Double color mold is becoming more and more popular in the market at present. This process can make the appearance of the product more beautiful, easy to change color but can not be sprayed, but the cost is expensive, also needs high technical requirements.
  1. The two shapes of Cavity are different, forming one kind of products respectively. And the two shapes of the Core are exactly the same.
  2. the front and rear mould of the die must be 180degree after the center rotates. This check action must be done at design time.
  3. pay attention to the position of the pinhole of the top, the minimum distance 210mm. Large mold must be properly increased the number of rod holes. Moreover, because the thimble attached to the injection molding machine is not long enough, we must design an elongated thimble in the mold, and the thimble will grow about 150mm of the mold base. 2 positioning rings must be designed on the back die floor.
  4. the total thickness of the front panel plus A board should not be less than 170mm. Please take a closer look at other reference data of this type of injection molding machine, for example, the maximum thickness of the injection mold, the minimum thickness of the mold, the distance between the top hole and so on.
  5. the water outlet of the three plate die is preferably designed to be automatically demoulding. Special attention should be paid to whether the ejection action of the soft rubber nozzle can be *. 6. the depth of the SPRUE in the front side does not exceed 65mm. The distance from the top of the upper side (SPRUE) to the center of the mold is not less than 150mm.
  6. in designing second injection moulded CAVITY, we can design a part of avoiding the first place of the product that has been molded by CAVITY. However, it is necessary to carefully consider the strength of each sealing site, that is, in the injection molding, will there be a plastic deformation under the large injection pressure, which may lead to the possibility of a batch front in the second injection molding.

  2. injection molding, the first injection molding product size can be slightly larger in order to make it in the second molding can be more tight with the other CAVITY, in order to meet the sealing effect.
  3. pay attention to whether the flow of plastic will be impulsive in the second injection process, so that the first molded product will deform its glue position. If this is possible, we must try to improve it.
  4. before A or B plate clamping, pay attention to whether the front mold Slider or Lifter will first reset and crush the product. In this way, we must try to make the A and B boards die first, then the SLIDER or LIFET of the front die can be reset.
  5. two CAVITY and CORE water distribution as far as possible, and balanced, the same.
12.99% situarion is to first inject the hard rubber part of the product, and then injection the soft rubber part of the product. Because the soft glue is easy to deform.

5 WAYS TO PERFECT YOUR PLASTICS DESIGN AND ENGINEERING

When you begin a plastics design and engineering project, the goal is to create and manufacture a quality injection molded component. To accomplish that, you’ll want to consider front-ending some essential parts of the designing and engineering process so the actual plastic injection molding manufacturing process will operate smoothly. This will ultimately save you time and money in the long run.
  1. Select The Right Material
This may be the most straightforward rule of the previous four. Determine what material is right for your part. Is this a medical part? An automotive part? What are the requirements? Does it need to be flexible or rigid? Does the part need to withstand extreme cold or hot temperature? What material do other similar parts use? These questions are just the beginning. Thoroughly research which material works the best for the specific part you’re looking to produce.
  1. Make Sure The Wall Thickness Is Uniform
Making sure that the wall thickness of your part are as uniform as possible to avoid warpage, sink marks, voids, flow restrictions and longer, uneven cooling times. If uneven wall thickness is essential to the part, try to strive for smooth transitions that gradually taper.
  1. Try To Avoid Undercuts
Undercuts make it difficult to de-mold your part. The undercut piece of plastic will get lodged inside the mold once the part has hardened and cooled, making it difficult to eject the part from the mold. When undercuts are necessary to the part, and not a byproduct, many manufacturers have lifting mechanisms and side actions to help de-mold the part.
  1. Try To Avoid Sharp Corners
Try to avoid designing and engineering a part with sharp, squared edges. Sharp edges, like 90-degree angles, produce parts with molded-in stresses. The results are weak points within the part, which leads to cracking and/or part failure. If your part must have a sharp corner, adding a radius or several radiuses will reduce the higher levels of molded-in stress. The radius will redistribute the stress and allow the material to flow more evenly, thus avoiding breakage or failure.
  1. Make Sure To Consider Warpage And Shrinkage
Materials cool and shrink differently when your injection molded part cools. Warpage and shrinkage are both kinds of distortion that can happen during the cooling process. Warpage distorts the dimensions and is often caused by excess stress on the part itself. Shrinkage occurs when there’s a difference between the linear dimension of the molded part and the mold itself. In order to prevent one or the other, pay close attention to the tooling, part geometry and processing of the part.

CHARACTERISTICS OF NUMERICAL CONTROL SPECIAL MACHINING TECHNOLOGY

With the rapid development of digital technology and numerical control machine tool technology, different types and different types of CNC machine tools have been introduced into the mold manufacturing industry. The processing requirements for the space surface and difficult processing materials in the traditional manual die processing methods have been solved, and the use scope of the processing materials has also been expanded in the same time. . In recent years, through the extensive application of NC special CNC machining technology, it can be found that it has the following characteristics:
1.NC special machining technology can perfectly process all kinds of materials with high hardness, soft texture and high melting point, and will not be controlled by any external forces. At the same time, no manual intervention is needed in the processing process, and the accuracy of the machining can be corrected and compensated by using the relevant software.
2. When machining parts that need high accuracy machining, CNC machine tools can use their better flexibility to solve the problem of diversity effectively. Therefore, NC special machining technology has no limitations on the strength of processed materials. He can even process parts of various materials.
3. For a very small hole in the part or a little slit, the NC special processing technology can also get very accurate numerical value, process it with very high precision, and the precise machining characteristics of the NC special machining technology can effectively improve the production efficiency, and the parts are very complex for some processing. Parts, production efficiency increased more, can reach ten times, or even higher.
4. Some CNC machine tools can be used in one machine, because they have a lot of replacement devices and can be replaced at any time. This can not only save the cost of the machine, improve the efficiency, increase the profit, but also save the area of the area to reduce the rent. Thermal stress, the remaining thermal stress can be cooled to make hardening and so on, and the size difference of each part can almost remain stable.

INJECTION MOLD MANUFACTURING: WHAT YOU NEED TO KNOW

Helpful Information for Injection Molding
Injection mold manufacturing plays a key role in a wide range of production engagements. One of the biggest benefits of this type of process is seamless mass production. Implementing injection mold manufacturing in your output cycle enables your business to replicate an infinite number of the same component in succession and with flawless results.
Beyond granting the ability to mass-produce specific parts/components, injection mold manufacturing also delivers many other benefits. An advantage to using this production option in a wide range of industries is the low amount of waste. Unlike traditional tactics that leave significant portions of materials behind after the cycle is complete, injection molding minimizes scrap remains. As a result, many business owners find this procedure both efficient and budget-friendly.
What To Consider Before Moving Forward With This Approach
While this type of manufacturing method delivers a wide range advantages, there are a few critical factors to consider before determining if it’s the right approach for your project. Some considerations include:
Initial Tooling
The initial tooling means designing and prototyping a mold tool. This requires working with a trusted partner to create the tooling to make a precise final piece to use for replication.
Lead Times
Once the prototype design is complete, output occurs rapidly. However, ramping up and working through tooling does take time. When considering various manufacturing options, you will have to evaluate lead times to know if you have the bandwidth for this type of process.
Changes in Design
Additionally, you will also want to consider if your design might change throughout the process. Once you’ve created the prototype, you will not be able to modify it without beginning the tooling process all over again. Changing your initial design may result in waste and scrap or even require you to start over completely, resulting in loss of both time and money.
Size of Product
The size of the product you wish to mass-produce can also have an impact on the manufacturing method you will use. Injection mold manufacturing works best with smaller items that can be created in a single cycle. If you require tooling for larger items that may need multiple cycles, you may want to think about other output options.
Choose the Right Provider
Perhaps the biggest consideration when selecting the right production method for your engagement is choosing the right manufacturer for your job. When screening through prospective vendors, look for a company that has extensive experience in your specific vertical. Knowing that your entrusting your business to a team with previous industry insight can have a major impact on your overall engagement. Some vendors may seem less expensive at first; however, moving forward based solely on price with a firm that doesn’t have the experience needed for efficiency can actually cost more in the long run.

EVERYTHING YOU DIDN’T KNOW ABOUT CUSTOM PLASTIC COMPONENTS

In today’s global market, the manufacturing industry has had to continuously evolve with the needs of a worldwide market place. One key area of change? Plastic molding and reproduction.
A cornerstone of many manufacturing endeavors, plastic, once a brittle, hard-to-manipulate material, has (through the introduction of various polymers) transformed into a strong, versatile and flexible product capable of use in a virtually endless litany of industries. From smartphones and computers to cars and medical equipment, today’s custom plastic components have truly revolutionized the way manufacturers throughout the world can respond to client requests and meet deliverable deadlines. How? By enabling manufacturing facilities to output an endless supply of identical custom plastic components that fit together with other pieces easily and seamlessly.
Important Benefits Of Using Custom Plastic Components
Before the process of custom plastic components was perfected, manufacturing firms had to continuously recast and reproduce various pieces and parts. Not only did this prove a major waste of time for organizations struggling to meet deadlines, repeatedly being forced to “reinvent the wheel” on a project could cause major quality concerns since each batch created could have its own distinctive set of esthetic and functional characteristics. Incorporating a process for custom plastic components instantly eliminates the possibility of varying quality levels in different batches in the same project. Instead, because every high-quality piece is created in an identical method, an instant (read: simpler and more easily affordable) quality assurance process is achieved.
Beyond an enhanced quality control procedure, custom plastic components also offer manufacturers an extensively streamlined overall production experience. Every identical piece delivers quick, reliable assembly. This optimal efficiency not only helps keeps costs at a minimum, but it also helps ensure that products are assembled and ready for shipment faster than other, more manual, processes.
Best of all, incorporating custom plastic components can also offer lower scrap/waste percentages. It’s no secret that the manufacturing industry can often find itself plagued with an exorbitantly high scrap ratio on various projects. Custom plastic components and their inherently high-quality output change this. By using unparalleled cutting precision on every batch, fewer materials are scrapped. Additionally, any leftover materials can be saved for future project runs to ensure that wasted raw materials are kept to a minimum while profits remain at a maximum.
What To Look For When Sourcing Custom Plastic Components Producers
As with any professional partnership, it’s important to do your research when sourcing a firm to produce custom plastic components for your organization. Training, skill level and experience are all critical factors to consider when wading through a potentially exhausting list of industry “experts” all vying for your business. Beyond operational tenure, it’s critical to also look for a firm that offers optimal confidentiality throughout your partnership. The vendor you choose will have access to an extensive range of proprietary product information. Finding a reputable and qualified firm like JasonMould Plastics that makes confidentiality a top priority is imperative to ensure that you receive the discretion you deserve throughout your project’s entire duration for optimal peace of mind and return on investment.

CUSTOM PLASTIC COMPONENTS

Quality Custom Plastic Components
Molded plastic has come a long way in recent years. Once a brittle, short-lived item, today’s molded plastics can be made from thousands of different polymers that provide durability, strength, and flexibility to the production of countless automotive, medical, electronic, and consumer products. These products provide the added advantage of creating consistently identical parts that require minimal assembly after production. Quality assurance is built in at a significant savings.
Custom plastic components are engineered by professionals to meet a client’s specifications. Then a die is created, and, for a fraction of other manufacturing costs, production begins, creating thousands of identical, high-quality units. Since each piece is identical to every other one produced, quality control is made simple and affordable.
How Are They Used?
These parts can be used to manufacture everything from lawn furniture to automotive OEM parts. Medical products, electronics, telecommunication devices, toys, and business machines are just a few other examples of how consistently identical, high-quality, affordable parts are used in today’s manufacturing.
Streamlined Production
Once a die is created, production is surprisingly fast and affordable. The parts that are produced are easily assembled and ready for shipment. Since complications are eliminated during the design phase, parts are reliable and consistent. Easy repetition makes the entire process work more smoothly, cutting costs and ensuring product quality.
Minimize Waste
Many other manufacturing processes are inherently wasteful. By using custom plastic components, raw material waste is significantly reduced. Well-made dies can last for years or even decades. Scraps of polymer left over from a previous product run can be used in the next run. By not wasting the raw materials, costs are cut and profits increase.
Seamless Logistics
Partnering with an injection mold manufacturer will not only cut production costs and boost product quality, it will also streamline the logistics involved with the manufacture and delivery of product parts. Nothing halts an assembly line faster than poor inventory control. The perfect part does no good if it is late being delivered. Working with a professional injection mold manufacturer means that your custom plastic components arrive on time, at your door, ready for use.
Confidentiality
It is imperative that companies protect their intellectual property rights and innovative designs. Working with reputable suppliers ensures that competitors do not learn more than they should about your product. Lost innovations mean lost sales.
Compare Manufacturers
There is a wide variety of injection mold manufacturers, which means it is important to understand what to look for. Companies that offer informative videos, customer testimonials, and extensive product information are far more likely to be reliable and protective of your interests. One way to compare suppliers is to visit their facilities. If the machinery and facilities are well maintained, it is more likely that they take their job and your order seriously.
Custom plastic components make it easy to save money while providing high-quality products, whether on short run, small orders, or extensive, global manufacturing efforts.
