Klassifizierung von Spritzgussformen:
Je nach Formverfahren: Warmarbeitsform und Kaltarbeitsform

Nach Formmaterialien: Metallformen und nichtmetallische Formen

Geteilt nach Produktionsvolumen: Musterform (einfache Form) und Massenproduktionsform

Divided by mold material: soft mold and hard mold

2. Mold types classified by molding materials:

Metal material molds are divided into casting molds, die-casting molds, stamping molds (bending, punching, blanking, stretching, shaping, flanging, etc.), forging molds (hot forging, cold heading, rolling, drawing, extrusion, etc.), powder metallurgy mold (isostatic pressing powder metallurgy, metal injection molding powder metallurgy, powder forging powder metallurgy, pressure sintering powder metallurgy), etc.

Non-metal material molds are divided into plastic molding molds (extrusion molding, blow molding, injection molding, compression molding, gas-assisted, vacuum suction molding, etc.), rubber molds, glass molds, ceramic molds, powder metallurgy molds (PTFE), etc.

Pretreatment of raw materials or inserts (not all raw materials or inserts require pretreatment – drying, preheating, depending on the degree of product technical requirements, type of raw materials, temperature conditions, for metal inserts, generally need to be pretreated in winter hot.)

Pay attention to the raw material drying (baking) process.

There must be clear drying process documents and operating procedures.

Detection and control of moisture content before injection molding.

The baking material equipment has a status mark and the equipment is in good condition.

The records of raw materials entering and leaving the warehouse are clear and clear, and are implemented in accordance with regulations without confusion.

Moisture-proof conditions during the use of raw materials after baking and during turnover (turnaround packaging and temporary storage conditions in the factory).
