In the spiral diameter selection, the first solution to be addressed by a piston manufacturer is not to choose a ready-made model, but to confirm that the amputated area changes the capacity, injection pressure and plasticized surface area. This step determines whether the subsequent spiral diameter, structure and material grade are well founded.

Each size of the screw structure serves solid transport, melting, refining, measuring and injection sealing. The diameter, long-range ratio, three-part ratio, depth, compression ratio and front-end components need to be considered as a system; local parameters appear to be stronger and do not represent the raw materials and cycles of the package that are more suitable for customers. Technical communication distinguishes between three types of objectives that must be met, desired improvement and acceptable. It is necessary to meet the hard boundary of the item for the determination of equipment and screws, and it is hoped that the improvement item will be used for the comparison of standards and specialized programmes, while the acceptable item will help to control costs and deadlines. This would avoid stacking all requirements on a screw and would make it easier for clients to understand the real value of each configuration.

Site information should preferably include both photographs, short videos and data sheets. Photos are used to identify machine interfaces, screw tails and front-end components, video can be observed to measure, buffer and abnormal sound, and data tables are used to calculate the rate of application, the need for plasticization per hour and the length of stay. If only partial information can be obtained, a list should be provided for confirmation, rather than a tentative condition being a definitive conclusion. The focus of the discussion here is on amputation of capacity, injection pressure and plasticized surface area, which must correspond to the customer ' s current production conditions and cannot be based solely on the maximum values in machine samples.

From a sales management point of view, a standard process that can be repeated should be established by co-locking the diameter of the product weight with material viscosity. 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 cost of the misconfiguration is not only the screw itself, but also the cut-off, the waste of raw materials, the testing of molds, the delay in delivery and the credibility of customers. Precautionary measures built around the pursuit of large-jet volumes at the expense of stress and metrology may be more economical than retrofitting in the event of a problem; a vendor can then move from a mere offerer to a partner capable of taking on technical screening.

Upon completion of the project, the results of the delivery were based on the utilization of the reductor, pressure residuals and plasticization time, and the size tests, material or thermal 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 selected in the diameter of the screw, the plant manufacturer could gradually establish a package, a trade package and an aircraft-type menu to allow sales to quickly identify general and special conditions, while at the same time placing a truly complex project under the timely review of an application engineer.
