How Injection Molding Plants Improve Productivity?

The hard indicator of management assessment is productivity

◆ Productivity = machine utilization rate * mold cavity full rate * production efficiency (actual mold cavity standard output achievement rate)

There is also one part related to quality, but because of the large daily output of the injection molding workshop, the one-time pass rate of quality is generally negligible.

Generally, injection molding factories often focus on machine utilization rate and production efficiency, and often ignore the mold cavity filling rate. The following focuses on how to improve the mold cavity filling rate.

One of the assessment indicators: mold cavity full rate

Because of the limitation of the molding cycle, it is difficult to improve the efficiency. But the normal maintenance and molding debugging of the mold is very important.

The one-time upper mold cavity full rate can be used as a hard index for the performance evaluation of mold technicians.

Except for the cavities plugged by the mold before the upper mold starts up normally, other problems should be solved by the injection molding technician, which will test the technical level of the injection molding technician.

If there is no management in this part, once the product is not good, the technicians may only know plugging the hole. Then, their technology will not improve after a long time. If this part is not curbed, the improvement of efficiency will become empty talk.

In case of few holes:

When the mold is full of 8 products, if one cavity is plugged, the efficiency will drop by 12.5%. When there are only two products in a mold full of cavities, if one cavity is plugged, the efficiency will drop by 50% and the output will be reduced. The more plug holes, the lower the output and the less profit.

Plug holes can be reported by the technician himself: machine number, mold, reasons for plugging holes, number of plug holes

For piecework wages, statistics or accountants refer to this report to calculate the number of mold forming holes, calculate employee wages and analyze efficiency. There is also no need to worry about the technician not reporting the actual number of plugged holes truthfully. Because whether it is calculated by piece or by hour, employee wages are calculated. If the hole is plugged and not reported, it will be inflated when calculating the standard production capacity. Then, because this will directly involve wage income, the operating staff will find a technician to report the problem.

Ask the technicians to report the plugging points truthfully. If there are more plugged holes in a cycle, then that means the technician’s skills are really not good or he is lazy and not serious about adjusting the machine. If there are too many plug holes during production, it will also increase the maintenance workload of the mold workers, and dissatisfy the mold technicians. So in this way, the injection molding technician will be serious about the plug hole, and can only delve into the debugging technology.

Managers who know key management will be very relaxed

There will be highs and lows in a comparison. Once the assessment is made, the level of technology can be seen from this.

Of course, it will always be difficult to do everything in the assessment, and there will always be some reasons of one kind or another. The more unfair the management, the more excuses and reasons employees have. But as long as the assessment is not a formality, it is definitely better than no assessment.
