Do you know the adjustment skills and precautions for injection temperature and cooling time of small injection molding machines? If you don't know, we'll follow Liansheng injection molding machine Let's get to know.
1. Injection temperature adjustment:
a. Plastic type and brand:
Different types and brands of plastics have different requirements for injection temperature. When selecting the injection temperature, it should be adjusted according to the actual plastic used. Generally, the plastic supplier will provide the recommended injection temperature range for reference.
b. Balance of melt temperature and mold temperature:
The temperature setting of the injection molding machine includes melt temperature and mold temperature. Melt temperature affects the melting and flow of plastics, while mold temperature affects the cooling and solidification of products. When adjusting, pay attention to the balance between the two to ensure the stability of the injection process.
c. Initial temperature and adjustment steps:
Before starting the injection molding operation, ensure that the injection molding machine is at the proper initial temperature. The adjustment shall be carried out step by step, the temperature shall be adjusted slightly and the change of product quality shall be observed. Avoid excessive adjustment to prevent defective products.
2. Adjustment of cooling time:
a. Product geometry:
Products with different shapes and structures have different requirements for cooling time. Complex products usually require longer cooling time to ensure uniform cooling inside and outside and reduce product deformation and defects.
b. Thermal conductivity of injection molding materials:
Different kinds of plastics have different thermal conductivity, so the cooling time needs to be adjusted according to the plastic used. Plastics with low thermal conductivity may require longer cooling times to ensure adequate internal solidification.
c. Cooling system performance:
The cooling system performance of injection molding machine directly affects the adjustment of cooling time. Ensure the normal operation of the cooling system and adjust it as required. Sometimes it may be necessary to increase or decrease the flow or temperature of cooling water.
3. Precautions:
a. Real time monitoring:
During the adjustment process, the quality and performance of the product shall be monitored in real time. In case of any abnormality, adjust the parameters in time to avoid the occurrence of defective products.
b. Record the adjustment process:
Record each adjustment process, including changes in temperature, cooling time and product quality. This will help to adjust parameters more accurately in future production.
c. Continuous improvement:
Regularly review and analyze the data of injection molding process to find room for improvement. Constantly optimize the setting of injection temperature and cooling time to improve production efficiency and product quality.
stay Small injection molding machine By carefully selecting materials, balancing temperature settings, and adjusting cooling time according to product structure, an efficient and stable injection process can be achieved to produce good plastic products.
