What about us:

We are engaged in making plastic mould, especially in dual-color injection mould. Our tooling department was set up in 2006, we have built more than 1200 sets mould until now, 700sets dual color moulds and another 500 sets single color moulds. More than half are customerizd design, our customer was from all over the world, such as India, Austrilia, USA, Korea, and so on. 

                                                                                                                                                                                                                                       

Working Step:

1.R&D We support customer R&D. Make the files or improve the design if you needed.       ↓ 2.Negotiation the quality, mold life, material, ton need of the machine, delivery time, payment item, ect.       ↓ 3.Place an order according your own design or you chooses our design.       ↓ 4. Mould According customers request to build the mould. Before make the mould, we send mould design to customer approval first, before move forward to production; we send samples to customer to confirm first.       ↓ 5. Sample shoot If the first sample come out is not satisfied customer, we modify the mould and until meet customers satisfactory.       ↓ 6. Packaging With anticorrosive oil and polybag in wooden case.       ↓ 7. Delivery Delivery goods by sea or by air, according customers requirement.

  

What about the dual-color injection goods:

Producing two color or two component injected molded parts from two different thermoplastic materials in one process, quickly and efficiently:

Two-shot plastic injection molding, co-injection, two-color and multi-component molding are all variations of an advanced molding technologyCombining hard plastics with soft materialsTwo step process performed during a single press machine cycleConsolidates two or more components thus eliminating additional assembly costs

The technology of injection molding continues to become increasingly sophisticated. Up-to-date fabrication technology allows processors to produce injection molded parts from two different thermoplastic materials. By combining these different materials with the ever-improving molding technology, complex functional parts can now be produced economically and efficiently in massive quantities.

The materials may differ in polymer type and/or hardness, and can be fabricated from molding techniques such as dual injection molding, two-shot molding, two color molding, two component molding and/or multi-shot molding. Whatever its designation, a sandwich configuration has been made in which two or more polymers are laminated to take advantage of the properties each contributes to the structure. The thermoplastic parts from these moldings offer excellent performance characteristics and reduced cost. 

How Does dual-color injection machine Work?

Two shot machine with two independent injection unitsMolding one part using two different materials or colorsTwo cavity mold (one + one)First material injected into first cavity, mold opens and rotates to second cavity position, mold closes and second material is injected. After sufficient part cooling, the mold is opened and the part is ejected.Critical factors: material(s) melt temperaturemold wall temperatureinjection speeddelay time between injectionscomponent part temperature

The two-shot plastic injection molding process requires a machine with two independent injection units, each of which shoots different material. The first material is injected through a primary runner system, as in a normal injection molding cycle. During the injection, the mold volume to be occupied by the second material is shut off from the primary runner system. The mold is then opened and the core plate rotated 180 degrees. The mold is again closed and the secondary runner system is connected to the volume to be filled. After sufficient part cooling, the mold is opened and the part is ejected.

The two-shot process can also be accomplished with an indexing system (a round table rotating around a horizontal axis) with a primary and secondary station. While the first injection is accomplished at station #1, the second injection is accomplished at station #2. Each injection station is run by an independent injection unit. This allows injection speeds and pressures to be controlled for each material being utilized.

What are the Benefits?

Lower part cost: savings in production, handling, assembly and inventorySimplifies the production process with higher quality fabricationEliminate secondary operationsImproves integrity of the productEnhances product features and appeal: tactile, ergonomic, cosmeticNew design possibilitiesPackaging applications where a secondary color is desired to give prodcuts a unique appearanceAdded features to improve part functionally: multiple colorssoft touch surfacesgaskets and seals

The real payoff of two-shot plastic injection molding of thermoplastic materials is an economic one. Parts of two different materials can be fabricated with the speed, efficiency and economy of thermoplastic processing. This eliminates the labor-intensive secondary operations used for so many years and replaces them with high-speed automated operations, to yield a more consistent, higher quality fabricated part at a significantly lower cost.
