2K Injection Molds (Contains OverMolding & Insert Molding)

2K mold also referred to as double-shot, two color mold, dual-shot, multi-shot and over molding or insert molding, is a plastic molding process where injected two different plastic resins together in a single mold or two separated molds.

Over molding and insert molding some times are separated to two molds to balance cost and customer’s production capability. we will provide best evaluation to you for which ways based on your needs. Normally this two type of molds increases handling work if you set up two molds working on two single injection machines or working on one 2K machine without pick-up manipulator.

Generally recommend double-shot ,which reduce the amount of scrap, plastic material, cycle times, work-in-process(WIP) , assembly and driving mold & production down costs.

2K Injection Molds Additional Features

In brief for 2K injection molds: one mold, two step injections, one cycle. The first plastic injection finished and then gates are closed, the mold is automatically rotated (Turn core insert or whole fixing side with180 degree ) or a part is transferred within the same mold (picked and placed by manual or manipulator)，then start the 2nd shot injection and different type of plastic are injected into the mold.

Benefits of Two-Shot Molding:

A more cost-efficient(i.e. less cycle time, simultaneously injection).

Reduce secondary handling process.

Reduce scrap rates.

High level of accuracy and repeat-ability.

Form-ability of multiple color and parts.

Good operability with automation.

Realize the Single Minute Exchange of Die (SMED)

2K Injection Molds
(Contains OverMolding & Insert Molding) Customer Example

The customer needed a two-shot wheel(soft tire + hard rims) for vacuum cleaner, also desired a non-slip function and soft handle. Mold principle was : Mold closes and the 20 cavities are filled with the first shot of hard plastic. meanwhile another side of 20 cavities soft plastic not be injected until 1st shot finished of hard side→ then mold opened → Core side turned with 180 degree→ Mold closed→ Hard side and soft side injected at same time → Both side injection finished and mold opened→ Soft side ejected complete wheel out, hard side without ejection controlled by injection machine → Core side turned back 180 degree and mold closed → Cycle operation.
