[Scene definition] How the waste of materials, which is frequently coloured, can be reduced by a screw to start from the real production scene of the plant, and not just from the diameter or price of the screw. It is recommended that the purchase price, waste, energy consumption, stoppage and spare parts be first collated, and that benchmarks be established for each of the three phases of start-up, stable production and refuelling. 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 ignored of the topic is the cost of a single eligible item and the full life cycle. Plants should establish a strict ranking of various feedstocks, establish boundaries according to the highest-risk conditions, and indicate variable and non-variable conditions in the demand table to reduce programme repetition. 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.

[Design Focus] The main line of this case is to replace the simple price with TCO and the current cycle. In the geometric and material programme, the retrofitting, reflowing and screwhead residual areas should be checked for retorting and retorting; and the retorting, retort and screwhead residual areas should be checked for retorting and retorting. 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 tests should be co-signed by production, quality and equipment, not to allow for a single-sector stand-alone model, and a comparison between old and new programmes using the same batches, moulds and sampling rhythms as new ones. 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, spare parts should be discharged early when the trend is close to the threshold, before the quality is out of control, and inspection cycles should be established for running 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 [comprehensive cost] cannot simply be a spiral price, and three life-cycle scenarios should be set with optimism, benchmarks and conservativeness to prevent a single hypothesis from magnifying the return on investment 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 three consecutive shifts be followed to avoid the use of single-temporal models to represent the volume of production, while providing for screwhead components or spare parts on key platforms and periodically reviewing the availability. When there is a significant change in the feedstock formulation, feed ratio, product structure or target node, the applicable boundary of “how the waste of frequently coloured raw materials can be reduced by a screw” should be reassessed, rather than defaulting that the old conclusion is permanently valid.
