[Scene definition] Why screw materials and thermal treatment records must be traced back to the actual production scene of the plant and not only to the diameter or price of the screw. It is proposed to organize the drawing versions, documentation, size reports, delivery and services first, and then to observe data at single, hourly and three scales per 10,000 items. 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. The plant shall bind the planned lifetime to the hours of operation per year, the type of raw materials and the frequency of maintenance, and shall determine priority by using the customer complaint and the internally defunct Paretto. 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 the geometry and materials programme, the dead-angle, reverse-flow and screw-head areas should be checked for re-coloring and refuelling; and the inside and wear-out of the cylinders should be integrated into the gap to avoid new screws being dragged by old cylinders. 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-valid] programme proposes to operate for at least eight consecutive hours, extracting 20 sims for each stabilization phase, recording extremely poor single modulus weight, storage time and bad black spot rates. The test shall measure both the temperature of the entropy and the temperature shown in the drums, confirm the contribution of the shearing heat, and measure the temperature of the entropy and the temperature shown in the drums, and confirm the contribution of the shearing. 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 cleaning, measurement, photographing and sampling should be combined in the shut-off window to reduce double-disassembly, and the abnormal twisting, storage timeout and material rebounding should be set as an early overhaul signal. 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 [comprehensive cost] cost statement should not 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 planned downtime would be charged separately from the unplanned downtime, which would include the loss of late delivery. 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 benchmarks be established for each of the three phases of start-up, steady production and refuelling, with the pre-repair signal being set for abnormal twists, timeout for storage materials and backlash for materials. When there is a significant change in the feedstock formulation, retrospective ratio, product structure or target node, the applicable boundary “why screw materials and thermal treatment records must be traceable” should be reassessed, rather than defaulting on the permanent validity of the old conclusion.
