The most common method of injection molding of

TPE material is used, which is faster and significantly improves production efficiency compared with other materials that require vulcanization process. But there are also some problems that lead to reduced productivity, such as sticking molds is a very annoying.

injection molds are divided into dynamic molds and fixed molds. In some areas, they are also called front molds and rear molds, male molds and female molds. Effective treatment methods for sticking molds with TPE material:

The draft angle of the rear mold can be made small in moderation, or not at all. If allowed, it can even be reverse drafted; the rear molds should be polished into mirrors as much as possible to increase adsorption, which is the opposite of hard rubber resin; from the perspective of molding process, the front molds can be connected to high mold temperatures and low mold temperatures with low mold temperatures; cross ribs can be added to the head of the needle.

TPE material injection molding processing and sticking mold is also used to treat the main channel sticking mold:

Flow groove thimble pin adopts the inverted shape of the flow channel pin style to increase the power of pulling the runner. Don’t worry about the flow channel being unable to be removed because this is soft glue. Of course, the angle of the inverted button can be started from a small amount and experiment slowly. If a general Z-shaped pin is used, the tension may not be enough, resulting in the flow channel being stuck to the master mold. The particularity of

TPE material, the smoother the mold surface, the greater the adsorption force, which is exactly the opposite of hard glue material, so the gate bushing can be discharged, retaining discharge marks of a certain thickness, and reducing the adsorption force of the runner; the formula of the TPE material can also be adjusted to lower the injection molding temperature.

If you need to purchase TPE materials or have any questions about the injection molding method of TPE materials, you can consult the Lien TPE manufacturer. We welcome everyone to conduct on-site inspections. All our TPE material application cases are designed around the user experience. Provide you with new polymer TPE materials that are healthy, safe and comfortable to touch.
