When injection molding power tools, the following precautions need to focus on:

1. Material selection: According to the use environment and performance requirements of power tools, carefully select the appropriate injection molding material to ensure that it has sufficient strength, toughness, heat resistance and corrosion resistance.

2. Mold design: The structure of the mold should be reasonable and the flow channel design should be scientific to ensure that the plastic melt can evenly fill the cavity and reduce internal stress and warping deformation.

3. Injection molding parameter control: accurately set injection molding pressure, temperature, speed and time parameters. Too high pressure may lead to flash, too low pressure may cause insufficient filling; Improper temperature will affect the flow of plastics and product quality.

4. Cooling system: Ensure the efficient operation of the cooling system of the mold, so that the injection parts are uniformly cooled to reduce uneven shrinkage and deformation.

5. Exhaust design: set the exhaust tank reasonably to discharge the gas in the cavity in time to prevent surface defects caused by trapped gas.

6. Release slope: In the mold design, to give enough release slope, easy to release injection parts smoothly, avoid strain.

7. Dimensional accuracy: strictly control the dimensional accuracy of injection parts, so that it meets the design requirements and meets the assembly needs of power tools.

8. Appearance quality: Avoid defects such as flow marks, shrinkage marks, bubbles and silver wire on the surface to ensure smooth and smooth appearance.

9. Production environment: Keep the production workshop clean and dry, reduce the impact of dust and impurities on injection parts.

10. Equipment maintenance: Regular maintenance of injection molding machines and molds to ensure the normal operation and accuracy of the equipment.

11. Personnel training: The operator should be familiar with the injection molding process and equipment operation, and strictly abide by the operating procedures.

12. Quality inspection: Strengthen the sampling and full inspection of injection parts, timely detection and disposal of unqualified products.
