[Scene definition] Which uniform indicators should be used for comparison among multiple screw suppliers to start from the real volume scene of the plant and not just to look at the diameter or price of the screw. It is recommended that the drawing versions, documentation, size reports, delivery and services be organized first, and that a uniform sampling method be used for the same product on different platforms to facilitate horizontal comparisons. 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 should set priorities using customer complaints and internally defunct Paretto, and divide needs such as appearance, size, strength and smell into necessary items and optimization. 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 geometry and materials programmes, the retrofitting, reflowing and screwhead residual areas should be checked for color change and refuelling; and screw diameter, effective itinerary and single-mode mass should be calibrated together to prevent long stops. 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 be conducted for a sufficient period of time under the normal maximum load to observe the twisting, temperature and measurement of drift, with stabilization points established at a medium rotation rate and a medium back pressure before the process window is gradually extended. 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, a single asset-numbered associated drawing, repair, up and down is used to record, and trend maps are created for the perforation, the reverse ring gap and the inside of the cylinder. 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 [integrated cost] cost statement should not be a single screw price, but should be analysed in conjunction with the time of storage, so as to avoid looking only at the total of the meter and ignoring the difference in output, and at a cost comparison programme per 10,000 eligible items, showing the impact of changes in production on the return period. 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 wear and tear trends, and that spare parts be released well in advance when wear and tear trends are close to the threshold and not processed until the quality is out of control. When there is a significant change in the feedstock formulation, retrospection ratio, product structure or target node, the applicable boundary of “which uniform indicators should be used for multi-snail supplier comparisons” should be reassessed, rather than defaulting that the old conclusion is permanent.
