Due to their good mechanical properties and excellent appearance, plastics are widely used in the automotive industry; whether it is the interior or exterior of cars, automotive plastics make cars more energy-efficient by reducing weight, corrosion resistance, toughness, design flexibility, and low cost. The automotive plastics market is forecasted to have a CAGR of 798%, reaching USD30.12 billion in 2027, exceeding USD9.12 billion in 2020. In recent years, with the increase in the consumption of electric vehicles, the improvement of production and manufacturing technology has driven the growth of the automotive plastics market.

Mold making process

1. The position of the main channel of the gating system is in the direction of contact between the nozzle and the cavity. The shape of the sprue is mainly the shape of a cone, which is easy to de-mold and will not damage the shape of the mold.

2. There are many requirements for the design of the runners in the gating system: first, different runners will be designed for different solution states; secondly, the corners of the runners should be smooth; The tail of Dao Unicom is used for cold material loading.

3. The gate of the gating system is designed as a point gate, and a small hole gate is set on the surface of the material to facilitate pouring. Only by performing multi-point pouring and using the relevant adjustment of the pouring point can the result of mold production reach an ideal state.
