Hot Stamping Tool, 2k & Double Injection Molding

We have  2k mold technology , so we can manufacture high quality  double injection mould . Here I will introduce the advantages in details as followings: Best elastomer adhesion to the plastic part No additional assembly steps Quick cycle times Low handling High degree of automation Stable production processes Economical part price

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.

2k molding  is more popular among the market. It is the case of 2 separate materials to form one cohesive components of which one material (say TPE/TPU) is molded "over" a "substrate" material (say rigid plastic or object). Two important concepts :- 1. In part design, you need to know how many substrate and overmold to stick by mechanical part design interlocks. 2. In materials selection, both materials attain a high level of molecular adhesion. For the  2k mould , Shinlone can finish the tool try by ourself, the 2K injection machine is 800T.

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 ?

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.

The direct  hot forming die  process is a three-stage approach. After heating up to 950 °C a blank is transferred to the pre-conditioned forming tools. Then the part is formed in an austenitic state. Afterwards the part is quenched in the colder tools. Applying a defined tonnage or engineering a specific gap between tools and the blank heat transfer conditions are adjusted. During this process stage the temperature in the blank drops from around 950 °C initially down to 200 °C. The average temperature of the tool in use is maintained near 80 °C. During this stage the transformation to a martensitic phase is driven by controlled heat transfer conditions that lead to characteristic cooling curves and therefore to final values for yield strength (YS) and ultimate tensile strength (UTS). Trimming the blank can be executed either directly in the tool or by means of a subsequent laser trim operation. We can provide  high quality hot forming tools , if you need, you c...
