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 machines 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.
The 2K technology with rotation table is a highly advanced and mature technology that offers significant advantages over traditional over-molding techniques. This technology enables the simultaneous injection of two colors, resulting in high efficiency and exceptional stability. Additionally, this technology can be applied to a wide range of products.
The process involves several steps. First, part #1 is injected. Next, the core side rotates 180° in the vertical direction. Finally, in the next cycle, part #2 is injected, followed by another injection of part #1. This process enables the production of high-quality products with exceptional precision and accuracy. Packson has extensive experience in this technology and can provide you with exceptional products and services.
The 2K technology with transfer by robot is a highly efficient and cost-effective alternative to the rotary table method. This technology involves the use of a robot arm to switch the molding part, resulting in significant savings in equipment investment costs. This technology is commonly applied to simple products and products with metal inserts.
The process involves several steps. First, part #1 is injected. Next, the robot arm transfers the part #1 to the second molding position. Finally, in the next cycle, part #2 is injected, followed by another injection of part #1. This process enables the production of high-quality products with exceptional precision and accuracy. Packson has extensive experience in this technology and can provide you with exceptional products and services.
The 2K technology with core-back method is a highly cost-effective solution that reduces the number of core sides required compared to the transfer method while still achieving the 2K injection process in a single mold. This technology offers exceptional cost efficiency and is commonly applied to functional parts without high surface requirements.
The core-back method also offers excellent quality stability, as the two molding steps can be completed in a single cavity, avoiding part warpage issues during mold open and part transfer. This method is more stable than the over-molding method, resulting in high-quality products with exceptional precision and accuracy.
The process involves several steps. First, part #1 is injected. Next, the core insert is set back to release space for the molding part. Finally, part #2 is injected. This process enables the production of high-quality products with exceptional precision and accuracy. Packson has extensive experience in this technology and can provide you with exceptional products and services.
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 injection molding 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 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
Plastic material flow systems-Runner and Gate
Cooling system for around cavity and core
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.
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.
