Knowledge

Material selection: Choose materials with good plasticity and processability, such as aluminum alloy, stainless steel, etc.

The heating temperature and insulation time should be accurately controlled to ensure the effect of material microstructure transformation and grain growth.

The cracking problem of thin-walled die drawn parts can be solved through the following methods

Poor rigidity, prone to chattering and tool vibration during machining, affecting machining accuracy and surface quality.

Whether to print the mold number, mold weight (KG), mold dimensions (mm), clear characters, and neat arrangement.

Select appropriate cutting tools according to the requirements of mold materials and processing, improve the sharpness of the tools

Due to the thin wall thickness of thin-walled products, plastic needs to quickly fill the mold during the filling process.

Reasonable casting structure design: avoid excessively thin casting wall thickness, evenly distribute wall thickness, and reduce thermal fatigue caused by local heat concentration

Mold steel is the decisive factor in mold quality, and choosing a reasonable steel is of utmost importance.

Mold material: 2316, 638 and other materials are used to prevent rust on the mold and water hole.

The clamping of thin-walled parts cannot be simply done with a three jaw chuck, and the clamping force is concentrated at three points

Thin walled molds need to work under high pressure, so they require sufficient strength to resist deformation and fracture.
