When the project involves a cycle improvement, the screwdriver programme must start from the real-life job of the client. Application engineers are required to organize plasticization time, cooling, mechanical action and molds into a set of verifiable, calculable and retroactive input conditions.

Old machine upgrades are the easiest to ignore system matching. New screws must be compatible with the needs of old drums, drives, brakes, heating, nozzles, control of travel and molds. Any build-up, speed-up or material upgrade should first measure the status quo, then determine whether the single replacement, plasticization component upgrade or the full retrojection of the unit. Calculates the nominal value to be converted to the actual condition. The machine often uses PS as a reference for the gel weight, which should be revised by density when using other raw materials; the weight of the product should be added to the main course, traffic separation and a reasonable buffer. The larger the diameter of the screw, the greater the theoretical capacity, but the pressure of injections per unit area under the same hydraulic pressure or servo system will decline and the resolution of the measurement of the small amount of the aerosol may also be variable.

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 on plasticization time, cooling, mechanical action and mould limitations, which must correspond to the customer ' s current production conditions and not be limited to the maximum values in machine samples.

Periodic decomposition can be used to identify real bottlenecks as the main thread for project advancement and to arrange for an evaluation of sales, design, process and customer participation. The evaluation focused on the completeness of the input data, whether the assumptions were confirmed by the client, whether the mechanical interfaces were matched, how standards and specialized programmes were selected, and who provided the acceptance data.

Special vigilance is needed to shorten the cycle significantly if the bottlenecks are not plasticized. Many of the post-sale disputes arise from inconsistencies between the design input and the actual production conditions, such as the customer ' s replacement of the raw material number, the increase in the return rate or the transfer of the screw to another set of moulds, while still requiring the maintenance of the original acceptance results. The configuration of the boundary and change management should therefore be included in the technical document.

Upon completion of the project, the result of the delivery was to model the ratio to total cycle improvement and to archive the size test, the material or thermal treatment certificate, the trial module recording and the maintenance of the recommendations. Sales teams can return after three months or a ton agreement to compare plasticization time, energy consumption, product fluctuations and wear and tear trends. For aluminum manufacturers and vendors, professionalism is reflected in the ability to translate the client language into engineering parameters and to interpret the programme into production, quality, maintenance and cost results that the client can understand. The development of standard processes around the cycle will not only improve the accuracy of this selection, but also create a reusable machine and application database.
