What is the standard injection mold development process?
Original: Original | Author: DGMF Mold Clamps | Publish Time: 2020-04-21 | 13392 Views | Share:
Before drawing the final assembly drawing of the mold, the process drawing should be drawn up, and it should meet the requirements of the workpiece drawing and process data. The size guaranteed by the next process shall be marked with the words "process size" on the drawing. If, after molding, no other machining is performed except for repairing burrs, the process drawing is exactly the same as the workpiece drawing.

Surface roughness

Mark one of the most applied roughnesses in the upper right corner of the drawing, such as "Remaining 3.2." Other roughness symbols are marked on each surface of the part.

Other content

For example, the part name, mold drawing number, material grade, heat treatment, and hardness requirements, surface treatment, graphics ratio, free-size processing accuracy, technical description, etc. must be filled incorrectly.

2. Proofreading and drawing review

The relationship between mold and parts and plastic parts drawings

Whether the material, hardness, dimensional accuracy and structure of the mold and mold parts meet the requirements of the plastic parts drawings.

Plastic parts

Whether the flow of plastic material flow, shrinkage holes, welding marks, cracks, and release angle affect the requirements of the performance, dimensional accuracy and surface quality of plastic parts. Are there any deficiencies in the design of the pattern, whether the processing is simple, and whether the shrinkage of the molding material is selected correctly.
