2k injection mould means moulding two materials/colors into one plastic part. 2k injection moulding processes two materials with different characteristics, colors or hardness levels into one final product. 2K injection moulding, also known as co-injection moulding or multi-material injection moulding (MMM).
2k injection moulding relies on special 2k injection mould and 2k injection moulding machine. In general, 2K injection mould have 2 cavities. In the production process, we first inject plastic into the cavity of the 2k injection mould. After hardening, the mould rotates, and then we inject plastic into another cavity to complete the 2k product. An example of 2K injection mouldi is a lunch box. This is a product made of hard plastic, but the lid has soft plastic edges. With 2K injection moulding technology, we produce complete products in two steps. It also includes bicycle handlebars, toothbrushes with soft handles, etc.
Using 2K injection moulding technology, we can avoid possible assembly steps, thereby saving costs.
2K injection moulding technology can seamlessly assemble 2 components, so the final product becomes more durable.
Various colors can be mixed in the moulding stage, the product is more attractive, and the aesthetic value is high.
2K injection is very suitable for the combination of hard plastic and soft plastic. In this way, the product can be covered with softer plastic, thereby improving user comfort. Of course, soft plastics are essential in waterproof products.
Finally, products can be customized according to user preferences
In general, this mould is more expensive than a single-color injection moulding machine, and you must run the mould in a 2K injection moulding machine. However, since assembly steps and labor can be omitted, these costs can be quickly recovered in most cases.
In addition, all plastic combinations are feasible, and some plastics cannot be fully bonded together.
The 2k injection mould is a special injection mould. Its upper mould can rotate by itself or with the help of a machine, and this mould also requires a special injection moulding machine. In addition to the corresponding changes to the injection molding machine, MingHao's 2k mould injection moulding technology is the soul of the entire technology. The mould is rotated and displaced to achieve the effect of simultaneous injection of different plastics.
Daily necessities industry, industry, electrical products industry, etc., Minghao 2k injection products are generally made of ABS, PC and other hard plastics with TPE soft plastics, such as washbasins, water buckets, toothbrush handles, mugs, two-color cups, two-color helmets, car armrests and household electrical insulation series such as power switches, mobile phone keys.
2K injection has many advantages in more complex products. It helps reduce costs, reduce assembly time, combine material properties and establish a strong connection between materials. Minghao Mould is happy to provide you with 2k injection moulding solutions or help you manufacture 2k mould to produce the required products. Minghao will select the correct material and determine the best processing method. In this way, we can ensure that the final product fully meets or exceeds your expectations. We can help you optimize the design of 2K plastic parts and choose the best material that meets the bonding requirements of process, 2K mould design, 2K mould manufacturing and 2k injection moulding manufacturing
