Selection Strategies And Details Of Mold Release Agent

Update:2022-03-18 00:00
Summary:

Mold Release Agent keeps pace with other advanced manufacturing technologies in the reinforced plastics industry. In the past, the industry norm for release agents has been to apply paraffin wax in successive layers with a long drying time between the wax layer and the mold. This long-term and labor-intensive use of mold release agents occurs in glass fiber reinforced plastic products (glass fiber reinforced plastic) Not widely used.

 

The successful demolding of injection molded products mainly depends on the reasonable design of the molding mold structure and the reasonable selection of the process parameters of the injection-molded products. In injection molding production, due to fluctuations in process conditions, sometimes it is difficult to demold the product. In order to ensure the smooth production of injection molding of products and avoid the extension of the product production cycle due to the difficulty of product demolding, the molding dies the surface of the mold cavity should be sprayed or wiped with a layer of release agent.

 

The choice of release agent should be determined according to the raw materials used for injection products. A more widely used release agent is zinc stearate, in addition to polyamide resin; there is also a silicone oil-based release agent, which has a good release effect but is more expensive. At present, the most widely used and more convenient operation is the use of spraying atomized mold release agents.
