2K Injection Molding

Packson - Expert in 2K｜Multi-shot
Multi-component molding is a highly efficient and cost-effective technology that enables the molding of custom plastic parts using two or three plastic resins or colors in a single operation, resulting in faster cycle times and flash-free products. As a leading expert in this technology, Packson has mastered the process and has been manufacturing parts using multi-component molding for many years.

With our state-of-the-art 2k injection servicess and advanced 2K technology, we are capable of manufacturing various types of 2K molds. As your competent partner in this area, Packson is committed to providing you with the highest quality products and services. We would be glad to support you in any way we can.


What is 2k mould?
2K injection molding, also named a double injection, two-color injection molding, or 2 shot molding, is a process used to produce molded parts from two different materials with two colors.

As the 2k moulding factories , we operate 2K injection molding at one machine and perform two injections in one cycle. For the first cycle, plastic material is injected into a mold. Then rotated automatically and mix another property of plastic which was injected into the mold by the second nozzle.

2k plastic injection moulding integrates two different grad materials like hard and soft material to make a perfect combination with production. Two color injection molding is widely used in a variety of industries and it also allows for using clear plastics, colored patterns, and new style designs which help to make functionality products like medical plastic parts and reach marketplace value.

2K Mold Design
2K mold design is a pivotal factor for molding success. Followings are factors that will make an influence 2k molding: dimensioning and location of the sprue gates, dimensioning of shear edges, flow aids, cooling and ejector techniques, etc. Here at Packson 2k moulding factories, we keep making good 2K mold designs and we are committed to making durable mold that is highly efficient operating and easy to make maintenance and molding production.

The followings are the points that we need to consider during 2K mold design:
Shrinkage of plastic material
Wall thickness
Cavity Numbers
Plastic material flow systems-Runner and Gate
Cooling system for around cavity and core
Ejection System
Air venting

Applications of 2K Injection Moulding
2K injection molding is perfect for combinations of hard and soft plastics and also if you want to process 2 colors of plastic in one product.

2K injection molding is a good way for you if you want to combine two different materials like hard material and soft material into one product by injection molding processing. We create full products in 2 steps by two color injection molding. The most common example made by 2K injection molding is bicycle handlebar, automotive button, toothbrushes with hard handle and soft handle piece, medical diagnosis machine control button, etc.

2K Molding Design Guide
The 2K injection molding allows us to integrate multiple properties into one product: for instance, layered products, combinations of hard and soft plastic for making different color combinations.

The 2K injection molding allows us to combine two different properties of the material with hard and soft plastic for making two different colors. 2k injection moulding has wide applications and many strengthes.

Here are some advantages Of 2K Injection Molding：
One-stop finished part without secondary processing and assembly steps
Excellent adhesion to the plastic part
Quick cycle times
The high degree of automation
High efficiency
Stable molding processes
Low-cost molding
