Eight ways to control the cost of injection molding process?

Answer 1

Production plant

The layout of the production plant focuses on two aspects: to meet the production demand conditions, according to the production process to optimize the layout at the same time, and to meet the requirements of flexible energy use under specific production conditions.

1. Power supply, to meet the stable production of electricity required at the same time there is an appropriate margin, not too much surplus caused by excessive reactive energy consumption.

2. Build efficient cooling water circulation facilities and equip the cooling water system with effective insulation and thermal insulation system.

3. Optimize the overall production layout of the workshop. Many production processes have sequential coordination, reasonable coordination can reduce the turnaround time and energy consumption, and improve production efficiency.

4. Consider the lighting and other plant equipment as much as possible to the most effective small unit for separate control.

5. Do regular maintenance of workshop equipment to avoid damage to utilities, which may affect normal operation and increase energy consumption.

The injection molding machine

The injection molding machine is the major energy consumer in the injection molding workshop, and the energy consumption is mainly for the motor and heating.

1. Choose the right injection molding machine according to the characteristics of the products. The “big horse-drawn car” type of injection molding process often means a lot of energy waste.

2. Choose an all-electric injection molding machine and a hybrid injection molding machine, which have excellent energy-saving effects, and can save 20-80%.

3. Adopting new heating technology, such as electromagnetic induction heating, infrared heating, etc., can achieve 20-70% heating energy savings.

4. Adopt effective heat insulation measures for heating and cooling systems to reduce heat and cold loss.

5. keep the equipment transmission parts well lubricated to reduce the increase in energy consumption caused by increased friction or unstable equipment operation.

6. Choose low-compression hydraulic oil to reduce the waste of energy for hydraulic system work.

7. Adopt parallel action, multi-cavity injection, multi-component injection, and other processing technologies can significantly save energy.

8. Traditional mechanical-hydraulic injection molding machine also has a variety of energy-saving drive system, instead of the traditional quantitative pump mechanical-hydraulic injection molding machine energy-saving effect is significant.

9. Regular maintenance of heating and cooling pipes to ensure that no impurities, scale blockage, or other phenomena occur inside the pipes to achieve the designed heating and cooling efficiency.

10. Ensure that the injection molding machine is in good working condition. An unstable process may lead to defective products and increase energy consumption.

11. Ensure that the equipment used is suitable for the products processed, such as PVC processing often requires the use of special screws.
