2024-06-19 19:02:49

In the manufacturing process of precision casting equipment, to ensure product quality and production safety, special attention should be paid to the following matters:

1、 Equipment selection and material preparation

Select appropriate casting materials: Select appropriate casting materials based on the requirements and actual situation of the workpiece, such as aluminum alloy, magnesium alloy, titanium alloy, etc.

Check equipment status: Ensure that the casting equipment is in good condition, including accuracy, stability, and durability.

2、 Preparation before casting

Mold preparation:

Keep the mold dry to avoid defects such as bubbles and shrinkage.

Mold preheating: Before casting, the mold should be preheated to gradually increase its temperature and avoid damage caused by sudden contact with high-temperature metal.

Pouring system design: Design a reasonable pouring system, including gates, runners, feed channels, etc., to ensure uniform flow of molten metal and avoid defects such as bubbles and shrinkage.

3、 Precautions during the casting process

Casting temperature control: Strictly control the casting temperature within an appropriate range to avoid unstable workpiece quality caused by high or low temperatures.

Casting pressure control: Reasonably adjust the casting pressure to ensure that the liquid metal can fully fill the mold cavity, avoiding defects such as shrinkage and porosity.

Casting speed control: Control the casting speed to ensure that the melt stays in the mold cavity for an appropriate amount of time, avoiding cold shut and hot crack defects.

Atmosphere control: Avoid oxygen and moisture in the air from entering the metal melt, which can affect the casting quality.

4、 Post casting treatment

Timely cleaning of the mold: When cleaning the mold, be careful not to scratch the surface of the mold to avoid affecting the next use effect.

Casting inspection: Conduct visual inspection on castings to ensure they meet machining accuracy requirements, such as dimensional accuracy, appearance quality, polishing requirements, etc.

5、 Equipment maintenance and upkeep

Regular cleaning of equipment: Remove residues from the equipment and keep the outer surface of the equipment clean.

Lubrication maintenance: Regularly check the condition of the equipment's lubricating oil to ensure its cleanliness and adequacy.

Electrical system maintenance: Regularly inspect the electrical system of the equipment to ensure its normal operation.

Maintenance of safety protection devices: Regularly inspect the safety protection devices of the equipment to ensure they are intact and undamaged.

6、 Safe operation

Strictly follow the operating procedures: strictly follow the relevant specifications for operation, such as controlling parameters such as casting temperature, pressure, and speed.

Personnel training: Regularly train equipment operators to improve their operational skills and safety awareness.

By strictly implementing the above precautions, the safety and efficiency of the Precision casting equipment manufacturing process can be ensured, product quality can be improved, and production costs can be reduced.
