Quality retroactively appears to be a conventional equipment selection and is more likely to deviate from the image, batch, heat-processing, inspection and customer type not being assessed at the same time. For the manufacturer of a pyrotechnics and screws, the right approach would be to establish a situational baseline before discussing specific configurations.

The effectiveness of the programme needs to be verified with the same materials, moulds and test methods. In addition to size and material reports, time measurement, buffer position, pressure curve, temperature, product weight, appearance and periodicity should also be recorded, with clear acceptance windows. Data-based delivery reduces disputes and facilitates subsequent replication. 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 graph numbers, batches, heat treatment, testing and customer types, which must correspond to the customer ' s current production conditions and not only to the maximum values in the machine sample.

In the context of this project, it is proposed to adopt the concept of “Librity tags associated with electronic archives”. First, to determine whether the available data support the choice, then to calculate the volume of reductive, pressure and plasticization, and finally to discuss the geometry, front-end components and material handling of the screws. If the standard scheme is able to cover the window, priority should be given to the standard configuration; if the lack of a unique number would leave open the risk that the historical configuration would not be located after the sale, the dedicated structure should be proposed and the increased cost, delivery and expected benefits indicated.

There is a need for special vigilance that the lack of a unique number will make it impossible to locate the historical configuration after sale. 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 delivery conclusion is based on a retroactive completeness rate and problem location time, and the size test, material or thermal treatment certificate, trial modelling records and maintenance recommendations are 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. Where the information is temporarily incomplete, the pre-selection scope and the list to be confirmed may be provided, but it should not be considered a final commitment. Freezing the configuration after the customer completes the chart number, batch, heat-processing, inspection and customer-type can reduce the number of wrong orders and facilitate the production, testing, installation and sale of the same version of data.
