How to select low residual screws from the real production scene of the plant, and not only the diameter or price of the screw, is the frequent change of colour production line. It is recommended that the target nodes, storage time, refuelling frequency and OEE be organized and followed up on three consecutive shifts to avoid a single test model representing the production status. The aim of this step is to establish comparable old programme benchmarks so that subsequent screw changes can be supported by data.

The easiest to ignore is plasticization, cyclical bottlenecks and long-cycle drift. Plants should indicate variable and non-variable conditions in the demand table, reduce programme repetition and check the remaining plasticization capacity on the basis of order peaks rather than average annual production. 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 in this case [design focus] is defined by a stable output rather than a short-term maximum speed. In geometry and materials programmes, the measurement segment should be synchronized with the required back pressure, without excessive back pressure to compensate for geometric deficiencies; and the reverse ring structure and reflow gap 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-valid] programme proposes to operate for at least 72 consecutive hours, extracting 50 sims per stabilization phase and recording the number of downtimes, maintenance hours and the combined cost per 10,000 items. The test should measure both the temperature of the entropy and the temperature shown in the material drums, confirm the contribution of the shearing heat and be signed jointly by the production, quality and equipment, so as not to allow a single sector to be independently shaped. 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 the number of duplicates, and inspection cycles should be established on the basis of operational hours and tons of processed raw materials. 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 [of the combined cost] could not be simply a screw price, but should be based on a cost comparison programme for every 10,000 eligible items, showing the impact of the change in production on the current period, and separate the planned downtime 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 a reference set of data be maintained before and after maintenance to determine wear and tear trends, while cleaning, measuring, photographing and sampling be combined in shut-down windows to reduce duplication. When there is a significant change in the feedstock formulation, feed ratio, product structure, or target node, the applicable boundary of “how to select low residual screws for the frequently colored production line” should be reassessed instead of defaulting that the old conclusion is permanent.
