[Scene definition] how to set the service terms for the delivery of screwdriver emergency spare parts is to start from the actual production scene of the plant and not to read only the diameter or price of the screwdriver. It is recommended that the drawings version, documentation, size reports, terminologies and services be organized first, and that defective photographs, production times and parameter curves be linked to the same number of times. The aim of this step is to establish comparable old programme benchmarks so that subsequent screw changes can be supported by data.

The most easily overlooked aspects of the topic are needs deviations, creation deviations and acceptance disputes. Plants should indicate variable and non-variable conditions in the demand table, reduce programme repetition and dismantle daily production into class beats, time available and loss of modelling. Vendors can make retroactive trade-offs between interoperability, earmarking and cost when there are clear values for product weight, daily production, customer quality caps and allowed stop times.

The main line of the case [design focus] is the management of the supply chain with uniform data packages and performance acceptance standards. In geometric and material programmes, the inner and worn state of the cylinders should be integrated into the gap so as to avoid new screws being dragged by old cylinders; and the contours between the reverse ring and the reflow should be assessed on the basis of material fluctuations and injection pressure. The final solution would also need to be compatible with the wear and tear of the cylinder, the drive, the physical velocity and the current cleaning process, and would not cover up co-operation or process problems with a single high-level material.

The new [comparison validation] programme proposes to operate for at least 24 consecutive hours, with a 30-mode extraction for each stabilization phase, recording the replacement time, the amount of excess waste and the first eligible time. The tests should be conducted using a uniform code to avoid different names for the same phenomenon in different shifts, and a comparison of the old and new programmes with the same batches, moulds and sampling rhythms of the same raw materials should be made in A/B. If only the first one is checked, it is easy to miss the risks associated with heat drifting, material stoppage, reversal loop return and prolonged wear and tear.

When the [stabilized production] spiral is shaped, the key platform should be prepared for a screwhead component or a full set of spare parts, and the serviceability should be reviewed on a regular basis, and a maximum number of repairs should be set for each drop and surface thickness recorded for the refurbishment. The time of storage, back pressure, screw velocity, noise and mass of the product shall be recorded in a uniform manner in the shift. When the above indicators change at the same time, the mechanical gaps and the state of the raw materials should be checked before the process is adjusted to avoid the use of parameters to compensate for hardware degradation.

The cost statement [comprehensive cost] cannot simply be a screw price, and the cost of inventory, maintenance and rust prevention should be calculated for the back-up screw, compared with the cost of emergency delivery, and the test moulds, cleaning materials, transitional materials and bad goods should be accounted for at real purchase prices. It is recommended that the cost per 10,000 eligible items be exported simultaneously, the cost per 1,000 operating hours and the estimated number of return months. When new programmes reduce waste, refuelling or sudden shutdowns, higher initial inputs are often offset during production.

The [Closed Ring Management] will eventually include drawing numbers, screwdriver materials, heat treatment, critical dimensions, portable tubes, process windows and acceptance data in the curriculum vitae cards. It is recommended that a reference set of data be maintained before and after maintenance to determine the trend of wear and tear, and to provide for cold start-up temperature protection and to allow recoiling to avoid cold-temperature forced storage. The applicable boundary of “how to set service terms for the delivery of screwdriver emergency spare parts” should be reassessed when there is a clear change in the feedstock formulation, resonance ratio, product structure or target node, rather than defaulting that the old conclusion is permanent.
