For the injection molding factory, the injection molding machine is like the pot that people cook every day. The raw materials are the ingredients, and the method of adjusting the machine is the seasoning. In order to make a delicious meal, the perfect cooperation of each link is inseparable. We must clean the tableware and pots at the end of each meal. It is for the normal use of these next time. Production equipment also needs cleaning and maintenance. TPM is the English abbreviation of Total Productive Maintenance. It is a full-staff production and maintenance mechanism that is comprehensively composed of independent maintenance, professional maintenance, and preventive maintenance, with the participation of all employees, aiming at the most effective use of equipment.

The implementation of TPM should start from the most basic 7S (organize, rectify, sweep, clean, literacy, safety, saving), improve and enhance the corporate image, clean and bright A working environment can improve productivity. Reduce equipment failures and ensure quality. So as to achieve the effect of reducing costs. It can greatly improve the mental outlook of employees and make the organization full of vitality.

During the Sino-Japanese War, the Beiyang Fleet with the most advanced equipment in Asia lost to the Japanese Navy. Why? On the one hand, because the Beiyang Fleet seldom exercises and is unskilled in the operation of ships and artillery batteries, it is always in a passive situation of being beaten; Scattered, dimensional accuracy deviation, resulting in a serious drop in the accuracy of the shells hitting the target, and finally the seemingly powerful Beiyang Fleet lost. Unskilled tools and lack of maintenance of weapons and equipment became the main factors in the defeat of this war. The lessons of history still have profound implications for us today.

First of all, we must use the basic system assurance tools such as on-site 7S, equipment maintenance (TPM), and visual management to ensure that problems occur as little as possible. Second, use the value stream analysis (VSM) and program analysis (ECRS) tools to discover the seven wastes and find key improvement points. Thirdly, use tools such as 5W2H, PDCA cycle method, 5 whys, and seven QC methods to solve problems such as waste, and use continuous improvement to continuously optimize. Finally, the use of Standard Operating Procedures (SOPs) and work compliance tools to perform and monitor our work over the long term enables good work practices to be precipitated and maintained.

Advanced equipment management is the most direct and effective way for manufacturing enterprises to reduce costs and increase efficiency. The main goal of TPM is to improve equipment efficiency, that is, to limit and reduce six major losses: equipment downtime losses, set-up and adjustment downtime losses, idle, idling and short-term downtime losses, speed reduction losses, residual, secondary, Loss of scrap (loss of defects), loss of yield (interval from installation to stable production). The overall productivity of any enterprise is measured in terms of inputs and outputs. To improve productivity, one of the ideas is to spend money on equipment investment and technological transformation; the second is to spend no or less money, relying on people, machinery, and methods to fully coordinate TPM activities.
