In the case of car parts, it is not the choice of an off-the-shelf model that is the first solution to be addressed by the car industry equipment manufacturer, but rather the identification of nylon enhancement, fuel resistance, long-term continuous production and traceability. This step determines whether the subsequent spiral diameter, structure and material grade are well founded.

The name of the industry itself is not an optional parameter, but it points to a quality focus and production rhythm. Car projects focus on long-term stabilization and traceability, medical projects on cleanliness, packaging projects on high speed, optical items on low pollution and low stress. Plant manufacturers should translate these industry requirements into verifiable screw and process indicators. It is recommended that customer information be broken down into five groups: products and moulds, raw materials, platforms, process objectives and existing problems. Product end logs of single weight, flowway, number of caves, wall thickness and appearance levels; ratio of feedstock end recorder number, melting finger, filling, flame retardation and retrofitting; terminal logs of tonnage, voltage, screw diameter, maximum travel, injection pressure and plasticization. All data are sourced and are marked, drawn, physical, measured or estimated by clients.

Material analysis cannot remain under PPP, ABS or PA names. The specific plate number, the percentage of the product or mineral filling, the flame-retarding system, the water-bearing requirements, the permitted stay time and the recommended processing temperature should be checked. Differences in the sensitivity of viscosity, wear, corrosiveness and shearing may be apparent in the broad categories of the same material, which change the compression ratio, the three-part ratio, alloy and surface treatment. The focus of discussion in this paper is to enhance nylon, fuel retardation, long-term continuous production and traceability, data that must correspond to the current level of production conditions of the client, and not only the maximum values in machine samples.

From the point of view of sales management, the establishment of a grinding-resort-resistible configuration by the material community should constitute a standard process that can be repeated. Each project saves original needs, computations, final drawings, test modelling data and client feedback, and can call on experience in the event of a similar machine or material, but there is still a need to reconcile key differences and not to copy the historical configuration directly.

The main risk of the scene is that a single generic screw will not cover many high-load materials. The issue of whether or not to be derived from a screw should first be excluded from drying, heating ring, thermal voltage, nozzles, reversible rings, wear and tearing of the material drums and changes in process parameters. The use of exclusions is more reliable than the direct replacement of components and also protects the time and cost of both the seller and the client.

Upon completion of the project, the rate of shutdown, size stabilization and lifetime were used as delivery conclusions, and the size tests, material or heat treatment certificates, trial modelling records and maintenance recommendations were archived. Sales teams can return after three months or a ton agreement to compare plasticization time, energy consumption, product fluctuations and wear and tear trends. With the continued accumulation of project data on vehicle spare parts, the equipment manufacturer could gradually establish a package, a trade package and an aircraft-type menu that would allow sales to quickly identify general and special conditions, while at the same time placing a truly complex project under application engineer review in a timely manner.
