Mould Plastic Injection Type and Structure Innovation

Mould plastic injection have evolved into various types based on product requirements:

1. Single-parting surface mold (two-plate type): The most basic type, capable of single or multi-cavity designs, suitable for large-scale production.

2. Double-parting surface mold (three-plate type): Adds a movable gate plate for complex structures with point-gating feed.

3. Side-parting and core-pulling molds: Use sliders or cores to form side holes/undercuts, solving demolding challenges for complex structures.

4. Automatic thread removal molds: Utilize a mold opening motion or rotation mechanism to automatically demold threaded parts.

5. Runnerless molds: Use adiabatic heating to maintain a molten runner state, eliminating congealed material in the gating system.

6. Right-angle molds: Suitable only for angle-type injection molding machines, with the feed direction perpendicular to the mold opening and closing directions.

Structurally, a mold consists of a gating system, a temperature control system, molding components, and structural components. The gating system (main runner, cold well, branch runner, and gate) directly impacts molding quality, and its cross-sectional shape and dimensions must be designed based on the properties of the plastic.

Qingdao Xueyu Molding Products Co., Ltd. is mainly engaged in the design and manufacturing of injection molds, injection molding and secondary processing (spraying, pad printing, ultrasonic welding, stamping), etc. For more information about mould plastic injection, please contact us.
