[Scene definition] How to assess the impact of the new screw on quality and cycle from the actual production scene of the plant with the DOE test cannot be based solely on the diameter of the screw or the price. It is recommended that baseline data, cross-tests, process capabilities and résumé records be first collated, 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 of the topic is the coherence between short-term improvements and long-term stability. Plants should examine the remaining plasticization capacity on the basis of order peaks rather than average annual production, and write quality standards into quantum sets, sample numbers, upper and lower limits and determination rules. 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 to determine whether or not to stereotype and reproduce using reversible data. In geometric and material programmes, the retrofitting, reflowing and screwhead residual areas should be checked for color change and refuelling; and the rudders should be checked, speed-rotation allowed and screw cores allowed, at the same time, to prevent increased capacity at the expense of mechanical safety. 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] program proposes a minimum of 48 hours of continuous operation, with a 100-mode extraction for each stabilization phase, and records the screw-back load, back pressure stability and daily production. The test shall first establish a stabilization point at a medium rotation rate and a medium back pressure, then gradually expand the process window, and also maintain sufficient time to observe the twist, temperature and measure drift under the normal upper load. 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 abnormal twister, the material overtime and the material rebound shall be set as an early overhaul signal, and the abnormal twister, the material overtime and the material rebound shall 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 [integrated cost] cost table cannot simply list the price of a screw, and the procurement price should be annualized in accordance with the expected useful life, to prevent low-price options from being frequently replaced at higher cost, and to set a minimum production threshold for a dedicated screw, re-comparisoning the generic formula when production is insufficient. 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 proposed to establish a record of refuelling weights, cleaning time and first eligible time, along with trend maps of pyroclastics, reversible ring gaps and the inner diameter of the cylinders. The applicable boundary “how to assess the effects of the new screw on quality and cycle using DOE tests” should be reassessed when there is a significant change in the feedstock formulation, feed ratio, product structure or target node, rather than defaulting that the old conclusion is permanent.
