New technology of two-color mold
Two-color injection molding machine is equipped with two barrels. Mold is single cavity, only first type of plastic (“hard rubber”) and second type of plastic (“soft rubber”) need in common. Required die and punch are single, which is fundamentally different from previous two production modes. After injecting first plastic into first barrel, wait for first plastic to partially solidify. Power cylinder drives isolation blades and retracts to be level with profile of punch. At this time, second barrel is injected with second plastic. After second plastic is completely solidified, injection molding machine opens and complete product is taken out. Then injection molding machine is shut down and next cycle begins. Obvious advantage of this technology is that it simplifies mold and reduces need for injection molding machine working space (you can use fewer two-color injection molding machines to reduce investment and reduce costs). Output can be doubled compared with previously used “encapsulation method”, defective products caused by “hard rubber” that has been contracted and deformed are re-inserted into mold cavity.
If you’re still looking for the good co injection footwear mold maker in China, we can be your another good choice.
