  • 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.

    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.

Product Assembly
PTMS has been providing plastic injection mold and injection molding parts to the worldwide customers, also die-casting, metal stamping, precision CNC machining parts, etc. So we would like to provide assembly service as customers’ need.

Secondary operations

Vacumm LineWe invested 1 secondary operations shop for painting, printing and assembly according to customers’ need in 2011. So our company can make additional service and make much more value for customers, the shop will provide painting for plastic parts or metal parts, printing stamping for plastic parts or metal parts, product assembly and package, etc. We also set up 2 new assembly lines for product assembly according to our new R&D office requested.

We invested 2nd operation processing shop but our capability for this is limited so we have to choose good 2nd operation processing plants in Shenzhen, our assembly shop is very strict with the 2nd operation processing partners, they should have much experience in plating and EVA package and others. We got a good partner for EMI plating as Vacuum Plating Factory in 2012, so we can provide vacuum plating.

Subcontract service

Assembly LinesWe have 2nd operation processing shop but we can’t provide all services to customers, so our company also can subcontracts service to close partners for customer if needed.The other 2nd operation processing service include laser printing for plastic parts or metal parts, hot printing for plastic parts or metal parts, plating for plastic parts or metal parts, clean room injection molding 100K class, complex product assembly, etc.

Our 2nd operation processing plants are very experience in printing, plating and laser printing, etc. The plants are very honest to PTMS, because we are long time business partner for many projects and they can control the quality and the total cost in a reasonable price, they have experienced QC technicians and many advanced inspection equipments, so QC will inspect the parts and defective parts will be taken out, the people will make new high quality parts for customers.

The plants can make the high quality parts with reasonable price. We are very strict with the plants and make value to them and the plants always make the high quality, reasonable price parts and perfect service to our customers. If you want to know product assembly gallery please check our product gallery site.

Summary

We have much experience in secondary operations and assembly for plastic parts and metal parts, in the same time, our company can control the quality and total cost. That’s to say, our assemble shop can do assembly with various product and for many industries.
