  • Two Color Plastic Custom Injection Molding
    Two Color Plastic Custom Injection Molding

    PTMS as a china plastic injection mold supplier, we are also china injection mold exporter for many years, so we have many years experience in plastic injection mold making and custom injection molding production. We knew the structure of plastic parts is very complex, so there will be many injection shot on the custom plastic injection mould, it also called multi shot injection molding.   The Multi shot injection molding refers to creation of multiple layers relative to the starting axis of the initial mold. In other words, the warm, heated materials are inserted into the mold in a very specific sequence one after another. This creates a layering effect between materials while maintaining relatively high-energy interactions at material boundaries. This is important because it implies that the inter-layer bonds are stronger in many cases than when the layers are applied to a previously cooled part, as is more closely the case of over molding. While there are other applications, this operation is preferred when varying molds (different geometries) are desired between material layers.   If you need to know more data of multi shot injection molding, please visit our website ptms-mold.com and contact us by sales@ptms-mold.com, we will learn and share more with you.

    PTMS as one of china custom plastic injection parts suppliers, also one of double injection molding manufacturers in china, we always provide high quality custom injection molding and double color injection molding to the worldwide customers. In the fact, the double color injection molding also called two component injection molding. We will share some data about double injection molding, two component injection molding describes insertion of multiple viscous materials injected simultaneously, as opposed to placing one material as an additional layer relative to another. In other words, it creates a sandwich-like structure where both materials mold around each other as dissimilar liquids, and exist in such a state at the same time. Relative to the part center, materials can be injected concentrically using the same mold/gate, or regionally using gates at different locations. If you want to find high quality plastic injection mold manufacturers, you can contact PTMS, for more please visit our website ptms-mold.com, we are a china custom injection mold supplier, also we are one of china double injection molding manufacturers, always make top quality custom plastic injection mold and injection molding to clients.

  • Cooling of Cavity and Core for Custom Injection Mold
    Cooling of Cavity and Core for Custom Injection Mold

    PTMS as a china plastic injection mold supplier, we are also china injection mold exporter for many years, so we have many years experience in plastic injection mold making, how to make high quality injection mold? The design is very important, as we know, the injection mold will be very hot when production in injection machines, so the cooling should be good, we will share the knowledge of injection mold cooling.   The injection mould is made of cavity and core, so it include two cooling, cavity cooling and core cooling. Cavity plate cooling by drilled holes. The cavity plate is drilled around the cavity insert and plugged with copper or aluminum taper plugs at the ends of openings. Using pipe connected at the inlet and outlet ports, water is circulated to cool the mold. Direct cooling of core insert (baffle system)—The core is drilled by keeping sufficient wall thickness. A baffle plate is located between the drilled hole, dividing the hole into two halves, allowing the water to contact the maximum area in core so cooling may take place. Annular cooling of cavity insert—A circular groove is made on the core for water circulation. To prevent leakage, O-rings are used above and below the cooling channel.   We can make top quality custom plastic injection mold with perfect cooling design, so the injection mould has a long mold life when custom moulding production, if you want to know more please visit our website ptms-mold.com, we would like to share and learn more from the worldwide plastic injection moulders.

    The Attributes of Plastic Injection Mold Cooling Design

    PTMS as a china plastic injection mold supplier, we have much experience in plastic injection mold making, also a multi-cavity injection mold factory, so we can make high quality custom plastic injection mold for customers. How to make injection mold? Firstly we have to design a perfect injection mold, the cooling design is very important in mold design and mold making, so we will share some desirable attributes of the mold cooling design that include: Constant mold temperature for uniform quality, Reduced cycle time for productivity, Improved surface finish without defects, Avoiding warpage by uniform mold surface temperature (warpage caused by nonuniform cooling), Long mold life. If you need top quality custom plastic injection mold and custom moulding, you can contact us, for more details please visit our website ptms-mold.com, hope we can design and make more high quality injection molds and injection molding for the worldwide people.

Injection Molding
PTMS always provide high quality custom precision plastic injection molding parts since 2002. We have 35 Japan and China advanced plastic injection molding machines, also experienced injection molding team work in our company and they know how to control cost and make high quality injection molding parts to customers.

Machines

50-130Ton Japan Injection MachinesWe have 2 injection molding workshops now, the first workshop running 15 sets precision molding machines which include 8 sets Toyo Molding machines, 2 sets Toshiba Molding Machines, 2 sets Nissei Molding Machines, 2 sets Double Injection Machines, 2 sets Sumitomo Molding Machines, 1 set Mitsubishi Molding Machine. The second workshop running 20sets injection molding machines which had installed robot for plastic parts and injection runner fall down automatically, it produce custom injection molding, over-molding and silicone compression molding, also make outstanding precision, high quality, fastest dry cycle times in the industry. Besides, we can also produce insert molding and two shot molding. Plastic injection molding parts are used for Home Appliance, Medical, Weapon accessories, Printer accessories, Automobile parts, Connector parts and etc.

Materials

Plastic ResinPTMS injection molding machines can run all types of resins from commodity to engineered grades, high temperature to filled materials, we only work with high quality plastic resin suppliers in the industry and confuse normal bad plastic resin so our plastic resin we used is 100% qualified, the plastic resin as below:

Common Resin: ABS, PC, PC+ABS, SAN, HIPS, GPPS, HDPE, LDPE, PP, PE
Engineering Resin: PP+GF, PPO, PPS, POM, POM+GF, PBT, PBT+GF, Nylon, Nylon+GF
Soft Resin: PVC, TPE, TPR, TPU, Silicone
Over-molding Resin: ABS-TPE, TPR, PC-TPE, TPR PC+ABS-TPE Nylon-TPE

We also request the suppliers to provide us certifications which include ISO, ROHS, and others. We can show them to customers for check. All the materials we use are 100% brand new because high quality product is our company’s life.

Molding

Auto Injection MachineWe improve our production equipment into auto injection molding machines in 2015, 20sets injection molding machine had installed robot for plastic parts and injection runner fall down automatically.So the parts are removed from the injection mold by robotics or conveyor systems, it makes reliable, efficient and cost effective to injection molding parts production. If you want to know plastic injection molding parts gallery please check our product gallery site. We can also make second operation for molding parts, such as printing, painting and plating as customer's needs.

Summary

We have advanced plastic injection molding machines and many years experience team in injection molding industry and 8 QC technicians for each shift. We also send customers the first samples for check, QC inspect the samples by inspection equipments like as CMM, Projector, 2DMI, Micro Glass, Height Altimeter, Block Gauge, Pin Gauge, L-Square, Callipers, Micrometer, hardness and etc. We send quality report to customers for check, such as FAI, SPC, CPK and etc. All the jobs we make are just for high quality plastic injection molding parts.
