[Scene definition] How the screw maintenance cycle of the terminal abbreviated plastics plant is designed to start from the actual production scene of the plant and cannot be based solely on the diameter or price of the screw. It is recommended that equipment criticality, refuelling methods, overhaul windows and spare parts be processed first, and then tiered by batch of raw materials to prevent the miscalculation of formula fluctuations as a matter of equipment. The aim of this step is to establish comparable old programme benchmarks so that subsequent screw changes can be supported by data.

The most convenient thing to ignore is the planned and unplanned downside risks. The plant should break down the daily production into class beats, time available and model exchange losses, and the daily production into class beats, time available and model exchange losses. 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 upgrading of the screws from consumables to a key asset for predictable management. In geometry and materials programmes, it is important to check whether the depth of the feed segment is stable, while avoiding feed mouth-to-mouth bridges, and to test the screw diameter, effective itinerary and single-mode mass 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] 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 rate of rotation and a medium back pressure, then gradually expand the process window, and then establish a stabilization point at a medium rate and a medium back pressure before gradually expanding the process window. 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.

Once the [stabilized production] spiral is shaped, the inspection cycle should be established at both running hours and the tonnage of processed raw materials, and a system of metal heterogeneity isolation and magnetic insinuation should be put in place, as well as a post-normal examination of the prism damage. 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 simply be a screw price, but should quantify the response time for on-site vendor support, spare parts delivery and failure analysis to TCO, in addition to a cost comparison programme per 10,000 eligible items, showing the impact of changes in production on the current 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 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. When there is a significant change in the feedstock formulation, feed ratio, product structure or target node, the applicable boundary of “how to develop the preventive maintenance cycle of the terminal retrofitting plant” should be reassessed rather than defaulting on the permanent validity of the old conclusion.
