2K Mold Manufacturing


2K Injection Molding

A Full Services Custom Plastic Injection Molding Company providing Complete Product Development to Mass Part Production in China. Low & High Volume Injection Molding, Insert Molding, Over Molding & Vertical Injection Molding

2K part design

  1. 壁厚之间的过渡应逐渐减少流动问题,例如后填充和气体陷阱。
  2. 应避免深,无法通风的盲袋或肋骨。
  3. Long draws should have a 3-5° draft per side to aid component ejection.
  4. TPE的厚度应小于或等于基板的厚度,以防止经扭曲。这对于长而平坦的几何形状尤其重要。
  5. Uniform wall thickness in product is preferred to obtain the best molding cycle time and avoid shrink mark. Wall thicknesses ranging from 1.5 mm-3 mm will ensure good bonding in most overmolding applications. If the part requires the use of thick TPE sections, they should be cored out to minimize shrinkage problems, reduce the part weight and lower cycle time.


We insist mold construction design, steel quality and precise manufacturing is the key to achieve two shot injection mold with excellent performance. Our mold design principle is the mold must be durable, high efficiency and easy to do the maintance and manufacturing.

  1. Shrinkage factor for both materials.
  2. 塑料成分壁厚,均匀的壁厚厚度优先。
  3. Number of cavities in the two shot injection mold
  4. Plastic material feeding systems. Runner and Gate
  5. Core and cavity cooling system
  6. Component ejection system.
  7. To avoiding burn mark, air vent is necessary.
  8. 注射成型Type

2K Injection Mold Manufacturing

To speed up the two shot injection mold manufacturing process without sacrificing quality, you need the right technology. We use UG to design and manufacture 2K molds. The 2K Mould manufacturing was done totally according to the 3D mold design. For manufacturing the 2K mold, we use different manufacturing machines such as Mikron CNC, AgieCharmiles EDM, Sodick Slow Wire Cut machine, Grinding Machine and Gun Drill Machine. After machining all the components, we have to measure the key size on the CMM machine. It is very important to avoid flash at the parting surface.
