Ningbo release agent: how to choose the release agent


  Mold release agentIn the past, the industrial standard for the use of mold release agents was to use paraffin wax layer after layer continuously, keeping a long drying time between the wax layer and the mold. This long-term and labor-intensive use of mold release agents occurred in glass fiber reinforced plastic products (FRP).

The smooth demoulding of injection molding products mainly depends on the reasonable design of the molding mold structure and the reasonable selection of the process parameters of injection molding products. In the injection molding production, due to the fluctuation of process conditions, the phenomenon of product demoulding difficulty sometimes occurs. In order to ensure the smooth production of injection molding products and avoid the extension of the production cycle of products due to the difficulty of product demoulding, the cavity surface of the molding mold should be sprayed or wiped with a layer of release agent.

  Mold release agentThe choice should be determined according to the raw materials for injection products. The most widely used release agent is zinc stearate, except polyamide resin. There is also silicone oil release agent, which has good release effect but is more expensive. At present, it is widely used and convenient to operate. Spraying atomizing release agent is used. There are release agents TG series methyl silicone oil, TB series liquid paraffin and TBM series castor oil sold on the market, which have good release effect.
