Eight reasons why an injection molding plant needs a manipulator

Nowadays, many people have this idea. It is becoming more and more difficult for our injection molding industry. For injection molding factories, "moment is money". To improve production power, it is necessary to race against time and use higher-speed, more flexible, and higher-load manipulators. , To realize the automatic production, so that the efficiency of production is even more powerful.

The use of manipulators can deal with many challenges such as high labor turnover, shortened delivery cycles, and safety issues. Factory workers change jobs more frequently, and some workers will return home during the Lunar New Year instead of going back to the factory. Employers must continue to train new workers, which will affect product quality and output power. Instead of choosing manipulators, there is no such concern. In addition, , The manipulator can ensure the consistency of the operation cycle, improve the quality, and be safer.

1 Save labor:

The manipulator takes out the products and places them on the conveyor belt or the receiving table. Only one person takes care of them or one person looks at two or more injection molding machines together, which can save labor. The active assembly line can save the factory land and make the whole plant planning smaller and smaller. Compact and beautiful. According to the current standard of workers, the monthly salary of a worker is two thousand yuan per month. The monthly cost of the second shift is calculated by analogy. We found that the investment in the manipulator is still quite small.

Two-cycle stability, higher efficiency:

People will lie and even make fakes, but machines will not. Employers produce and pick up parts, and the daily output value fluctuates. One person will find reasons to cover up their lack of homework. The machine production cycle of 20S is 20S, which will never change. It is convenient for production management. In the long run, the boss’s benefit is because the robot is used, the same plant, the same equipment, and the same conditions. Because of the stability of the production cycle, it will improve virtually. The output value, and the progress of this part of the output value is the net profit.

For example, if the injection cycle of the product is 20 seconds, each shift should get 2160 molds. However, the general production data shows that it is difficult to achieve 2000 molds, especially the night shift is more difficult to achieve 1900 molds. If the robot is used for production, each shift should be able to achieve It can achieve about 2100 molds, with an average of about 500 molds per day. Assuming that each mold is calculated at 0.3 yuan, each machine can increase by 150/day, and the monthly increase is about 4,000 yuan. It only takes a few months to calculate with an inclined arm manipulator. You can recover the cost.

High security:

The work safety of workers is ensured, and there will be no work-related accidents caused by neglect of work or fatigue. Let people enter the mold to take the product. If the injection molding machine malfunctions or the button is closed, there is a risk of injury, especially for two-shift three-shift work, it is easier to show physical fatigue at night, and it is easier to cause safety accidents. The manipulator can ensure safe production, especially in large injection molding machines.

4Increase power:

The product production time of each mold can be fixed, and the same plasticizing time, injection time, pressure holding time, cooling time, and mold opening and closing time can be easily improved. The product yield is calculated based on the injection cycle of 30 seconds, and the time of manual removal It is 6 seconds, and the manipulator takes out 1.5 seconds. With a 15-kilowatt 120-ton injection molding machine, it takes 8 hours to manually take out the product and calculates that it can form 800 molds. It can be increased to 915 molds with a manipulator. The output power has increased by 14%. The 8-hour injection molding machine consumes 120 degrees of electricity (with One kilowatt per hour of electricity accounting) After using the manipulator, the power consumption can be saved by 120*14%=17 degrees.

5 Save materials and reduce costs:

Uncertainty when the personnel are taken out will result in product shrinkage and deformation (if the material tube is overheated. The need to reinject the material will spoil the material). The manipulator is always fixed when taking out, so the quality is stable.

6Improve product quality:

The newly formed product has not been completely cooled, and there is residual temperature. Hand marks will be formed when taking it out by hand, and the product can be taken out with uneven force due to uneven manual removal. Such as active demolding, the product will fall and cause bumps. It is contaminated with oil and produces defective products. The manipulator selects the non-grain suction tool with uniform force, the mold is fixed at all times, and the mold temperature is normal, which can reduce the product defect rate and greatly improve the product quality.

7 Avoid mold damage:

If the worker fails to take out the product, the mold will be damaged. If the manipulator fails to take out the product, it will take the initiative to alarm and shut down.

8 Progressive competition:

The use of manipulators can improve the image of the workshop, ensure the quality, accurately calculate the output value, and increase the intensity of corporate competition.

High-quality customers also expect to choose injection molding manufacturers with robots to cooperate. The use of robots largely overcomes the laziness of labor, and can accurately calculate the daily output value and delivery date. The use of manipulators can increase the competitiveness of enterprises, and it is the biggest trend in the future.

For other things, let’s calculate the value of the manipulator according to the labor salary and calculate the 17% tax deductible according to 55,000. The actual value of the product is 45,650. According to the monthly salary of the second shift worker is 4 thousand, according to the conservative start-up practice of the equipment is 9 months, the worker's salary is 36,000 according to the practice, which means that the cost is recovered in 13 months, which does not include the daily extra calculation. The production capacity of the injection molding machine and the electricity cost savings among others.
