  • 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.

Plastic Injection Mold Making

What is a high quality Plastic Injection Mold? We specialized in high quality injection mold making since 2002, the mold standard include HASCO, DME, RABOURDIN, JIS and LKM. PTMS specialized in high quality plastic precision injection mold making since 2002, all mold makers are 5-15 years experience on mold making and very experience for USA, Europe, Australia, Japan standard.


Machines

We have many advanced machines for mold making,EDM Machine such as 10 sets CNC machine, 4 sets Wire Cutting Machine, 2 sets Slow Wire Cutting Machine, 12 sets Milling Machine, 8 sets Grinding Machine, 15 sets EDM machine and Mirror EDM Machine, Auto Grinding Machines, MAG Grinding Machines, Polishing Machines and etc. Also outside good supply chain allows our experienced mold makers to meet compressed lead times while maintaining our reputation for quality injection mold. From single cavity & prototype injection mold to multi-cavity and family injection mold, mold maker are fully equipped to meet your unique tooling challenges. Our mold making shop is geared to work with injection molds from the small to medium to big size range, i.e. injection mold that are designed to run in presses of 800 tons and smaller.

Mold Making


Plastic Injection Mold

We just choose good mold components partner to work, such as LKM mold base, Mold Master, Gunther and etc, it makes sure the high quality mold components at the first time. The mold maker also check related important dimensions of mold base, cavity, core, inserts, lifter, electrodes, the mold designer have a meeting and discuss with mold makers about production every days, they will solve some questions in mold making, project manager also give some valuable comments to the mold makers. If you want to know plastic injection mold gallery please check our product gallery site.


We keep in touch with customers during mold making and discuss some problems with them, we also send customers CPP (CRITICAL PATH PLANNING) to show mold making plan progress and actual progress. Normally mold making progress like as Mold Detail design-Material preparation-Mold base received-Cavity processing-Core processing-Electrode-EDM & Wire Cut-Slide/lifter processing-Moldbase processing-Final fitting-Polishing-First Shot+Sample-FAI Report, we will send the first samples to customers for check and we will modify the mold if some questions, but normally our first molding parts samples will be perfect, that’s to say, our mold making capacity is very strong!


Additional
