(b) For end-of-pipe aggregation plants, to explain the screwdriver focus of the whole electrodynamic and hydraulic plume, which combines product, raw material, platform, production, life cycle and life data to reduce the cost of scrap, shutdown and life cycle.

全电动与液压注塑机的螺杆选型关注点

[Scene definition] The screwdriver focus of the whole electric and hydraulic refiller needs to start from the real volume scene of the plant and not just the diameter or price of the screw. It is suggested that the process be separated from the actual on-board values by first collating the amount of glue, the screw diameter, the process, the twist and the maximum rotation, so that control deviations can be detected. 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 that the platform capacity matches the quantity of the product. The plant should bind its planned lifetime to the annual operating hours, the type of material and the frequency of maintenance, and break the daily production down into class beats, time available and loss of modelling. 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 in this case is to balance accuracy and capacity within the safe utilization factor. In geometry and materials programmes, priority should be defined between interoperability and speciality to prevent over-earmarked conversion difficulties, while the inner and worn state of the cylinders should be integrated into the gap between alignments to avoid new screws being dragged by old cylinders. 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 validation] programme proposes to operate for at least 24 consecutive hours, with a 30-mode extraction for each stabilization phase, recording the replacement time, the amount of excess waste and the first eligible time. 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.

Once the [stabilized production] spiral is shaped, spare parts should be discharged early when the trend is close to the threshold, and not processed until the quality is out of control, and the key platform should be prepared for screwhead components or spare parts, and the availability should be periodically reviewed. 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] could not simply be a spiral price, and the cost of passenger litigation, return of goods and additional overhaul should be classified as loss of quality, with more than just counting off-board scrap, in addition to the analysis of single-unit energy consumption in conjunction with storage time to avoid looking at the total of the meter and ignoring output differences. 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 qualifying time, while combining washing, measuring, photographing and sampling in shut-off windows to reduce duplication. When there is a significant change in the feedstock formulation, retrospective ratio, product structure or target node, the applicable boundary of the “heavy point of concern for the whole electric and hydraulic plume” should be reassessed, rather than defaulting that the old conclusion is permanent.
