In response to retrofitting of transparency material, customers often ask for prices or deadlines, but the suppliers of transparency equipment should first check the retropurification, heat history, colour and volatilizer. Only by quantifying these conditions can the standard screws have an interpretable boundary with the choice of a dedicated screw.

Additions and fillings change the demand for currents, frictions, wear, corrosion and mixing. The configuration is not limited to additions, but also focuses on particle form, carrier, fibre length, decomposition products and batch fluctuations; where necessary, the screws, drums, retroring, nozzles and dry delivery systems are evaluated together. 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.

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 refill cleanliness, thermal history, colour and volatilizers, which must correspond to the customer ' s current production conditions and not be limited to the maximum values in machine samples.

The implementable option is to adopt low-sustain clean-up structures and limit the return rate. The quoted documents should include both the applicable raw materials, the range of recommended voltage, the permitted turn-off and back pressure, the size of the interface, the material and thermal treatment, and the need for re-evaluation when marking subsequent changes to the material or the mould by the client. This would prevent the use of earmarked programmes in completely different conditions.

The main risk to the scene is that a small amount of pollution will also be magnified on the transparency. 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.

Ultimately, the objectives should be judged through black dots, fog and yellow transformation programmes. If the result fails to meet the standard, each adjustment and result shall be recorded in five directions, by raw material, equipment, molds, process and screw, so as to avoid the loss of causal judgement by modifying multiple parameters at the same time. 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 establishment of standard processes around transparent retrospect not only improves the accuracy of this selection but also creates reusable machine and application databases.
