In the standard machine mixer menu, it is not the choice of an off-the-shelf model that is first to be addressed by a manufacturer of retrospectors, but the recognition of tonnage, diameter, material packages, grinding grade and application. This step determines whether the subsequent spiral diameter, structure and material grade are well founded.

The value of technology sales is to reduce the risk that customers will miss the equipment and accessories. Sales personnel need to close the demand questionnaire, technical evaluation, quotation boundaries, delivery nodes and post-sale recording, so that customers know what data each recommendation is based on, and that internal design and manufacturing teams have consistent information. 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.

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. The focus of this paper is on the tonnage, diameter, material packages, grinding grade and application industries, which must correspond to the customer ' s current production conditions and not be limited to the maximum values in machine samples.

An implementable programme is the establishment of a basic, grinding, corruption-resistant and dedicated hierarchy. 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.

It is difficult to understand that sales are likely to occur after delivery if they are placed quickly and on an empirical basis with too few options. The success of a single test module does not represent long-term stability, particularly for projects with high filling, high temperature, frequent colour change or multi-molecular co-plasms, and needs to look at changes in batches of material, the length of continuous production and the accumulation of wear and tear.

It is recommended that clients set clear floors and floors around the selection accuracy rate and the efficiency of the offer, rather than just " running well " . Quantification criteria may include measurement of time fluctuations, extremely poor product weights, number of black dots, change time, hourly production or ton wear and tear, with specific projects choosing indicators that really affect business outcomes. Therefore, the standard machine menu should not follow the simple logic of “system-size screw”. Only by accounting for products, feedstocks, tonnages, voltage, screw diameter and target cycles will the standard screws have a clear scope of application and the dedicated screws have a reasonable design basis and return on investment.
