  • 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.

Silicone Rubber Compression Molding

PTMS started to produce high quality silicone mold and silicone rubber compression molding to the worldwide customers since 2010, we invested a silicone molding production line for silicone rubber parts processing as customers’ need, all the mold makers have much experience in silicone mold making, they knew how to control the cost to produce high quality silicone rubber compression molding.


Machines


We have some advanced machines for silicone rubber compression mold making and silicone rubber compression molding, such as high speed CNC, EDM, Wire Cutting, Grinder, silicone molding machines from 50-100ton. The workers have 5-10 years experience in operating machines, it is one important aspect to make high quality silicone rubber mold and silicone rubber molding parts.


Silicone rubber compression mold


silicone compression moldOur silicone rubber mold makers have much experience in silicone rubber mold making. We can make single cavity and muti cavity based on customers’ request, the steel of core and cavity is imported from German and Japan, its include P20, 2311, H13, 2344, 236, AdC3, S136, 2312, 2379, 2316, 2083, etc. The mold base include HASCO standard, European standard, World standard. The mold base materials we used are LKM, HASCO, DME, etc. The surface finish as Texture and high gloss polishing.


Silicone mold making is according to drawings, such as 3D drawings with igs, stp, x_t format, 2D drawings with DWG, DXF, PDF or JPG format. If you do not have 3D drawings, please offer 2D drawing with estimated part weight, but if you do not have 2D drawings, please send us the samples for check, we will make silicone mold design as the samples and then start to make silicone rubber compression mold. The mold will be packed by wooden box before delivery, shipped by sea or air, we will delivery it as customers’ request.


The silicone mold designer will have a meeting and discuss with the mold makers about production every days, they will solve some questions in mold making, project manager also give some valuable comments to the mold maker. 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 and trial samples and try-out report to customer for testing. We will modify the die-casting mold if samples not accepted, but normally our first testing samples are excellent.


Silicone rubber compression molding


silicone molding machineWe have some advantage silicone molding machines and experience people in production line, so they can control quality and the cost, the materials we often used is silicone rubber, we just purchase the materials from the reliable material suppliers who can provide ROSH, SGS and CE report, so we can make sure high quality silicone rubber materials.


We can make various silicone rubber compression molding parts, such as silicone keypad, silicone automotive key case, silicone rubber bottle sleeves, silicone bottle cap, silicone sealing gasket, silicone phone holder, rubber cover and etc. We can also make the second operation for silicone rubber molding parts, such as silk-screen printing, painting, laser etching, UV finishing and PU finishing. The silicone parts will be packed by pp bag in carton and than delivery by sea or air, anyway, we will pack the silicone parts as customers’ need.


The advantages of Silicone compression tooling:


1. The short lead time for the compression mold manufacturing, normally it is less than 15 days, but sometimes we can make out the molds within 5-8 days.

2. The single cavity silicone mold cost is about 2% cost of the injection mold for rubber molding and 10% cost of the mass production compression mold cost.

3. It is easier to make the rubber product undercut with compression molding.

4. It is easier to have the over molding and insert molding.

5. It has the various color rubber parts manufacturing without additional charge.
