The process of hot forming die

Hot forming die is a temperature- and time-dependent process. With this method, parts are formed in their soft state at elevated temperatures and then quenched in the tool.

  • The hot forming process consists of the following steps:
  • Heat treatment in furnace
  • Transfer from furnace to press and drawing tool
  • Plastic hot forming
  • Quenching in the closed, cooled die
Parts produced by hot forming tools are characterized by high strength, complex shapes and reduced springback effects. Optimal material behavior is achieved through the structural transformation of austenite into martensite. The most commonly used material in hot forming is Boron steel 22MnB5, which is available from many steel manufacturers.

Advantages of 2K injection mold

图片
Last news is an introduce of  2K injection molding . Here I will tell you the benefits of  double injection molding  as followings: excellent bonding  between components design  (colour combinations, information brokerage, marketing possibilites) soft touch or non-slip coverage  (to obtain certain grip control or for ergonomical reasons) sealing functions  (closeness against dust and condensation water, compactness versus various fluids) rigide/flexible composites  (with good damping characteristics) After know this, have you learned the  2K mold ?

2 major advantages of 2K injection moulding

图片
One of the major advantages of  2K injection moulding  compared to overmoulding is that the polymer to be injected is still hot and has not shrunk yet. This virtually excludes the risk of burrs being formed on the second component. In addition, the surface is still 'virginally' clean, enabling good molecular adhesion. Another significant advantage of    2K injection moulding   is the cycle time gained, the constant process and the fact that manual insertion is not required, thus avoiding the risk of damaging the first component.

An introduce of 2k mold

2K injection molding  is an innovative manufacturing process used to produce complicated moulded parts in multiple materials. Which can be used for a variety of product designs across all industries. Double injection molding  optimises the co-polymerisation of hard and soft materials to create a powerful molecular bond. Ming-Li uses thermoplastic elastomers and plastics for the 2K molding process as traditional thermoset compounds. It is not suitable.
