Main points of Bakelite mold design:

1. When forming bakelite powder, the front temperature of the barrel is 80℃~90℃, the rear barrel temperature is 60℃~80℃, and the mold temperature is 160℃~180℃. Therefore, the mold design requires a heating device, usually using a heating tube .

2. The mold cavity and core chrome plating can make the molded product easy to be injected.

3. Gas will be generated when the cross-linking reaction occurs after the bakelite powder is heated. Therefore, when designing the mold, the exhaust groove must be designed at the joint line or the end of the flow channel. The depth is usually 0.03~0.05MM, and the width is 4~6MM.

4. Bakelite products have high hardness and require high mold temperature, so it is necessary to choose wear-resistant mold steel. Steels that generally require good steel strength, wear resistance, and heat resistance, such as powder tool steels.

5. Bakelite powder contains various fillers, especially containing hard mineral fillers. The hard mineral fillers wear the mold wall like a frost. Under the high-speed melt of the melt, the flow channels and cavity of the bakelite powder injection mold are very worn. Seriously, especially the gate. Therefore, the bakelite gate is usually used as an insert, so that it can be replaced at any time. Because of this, the service life of the company's bakelite mold is set at: 250,000 molds.
