When the project involves high light and exterior items, the screw programme must start from the real production tasks of the client. The brand equipment sales consultant needs to organize colour, glitter, silver silk, black dots and combinant requirements into a set of verifiable, calculable and retroactive entry conditions.

The core of the demand phase is not to immediately give a screw model, but to convert the client ' s product target into a calculable data. Product weights, project sizes, wall thickness, flow ratio, number of lacquers, flow weights, material plates and target cycles must be placed in the same record; if one of them has not been identified by the customer, it should be clearly marked as a hypothesis and the sales calibre should not be mistaken for final technical condition. 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.

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 the discussion here is on colour, glitter, silver silk, black dots and mix requirements, which must correspond to the customer ' s current mass production conditions and not be limited to the maximum values in machine samples.

The implementable option is to translate the gap criteria into cutting, refining, exhausting and cleaning requirements. 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 of the scene is that a mere description of “good looks” cannot create an enforceable configuration. 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.

The focus of the validation was on the appearance pass rate and the color-release time. The test shall use the actual material and representative moulds of the client, retaining the batch number, dry condition, ambient temperature and sample number. When compared to old schemes, equipment, moulds and major process conditions other than screws should be as consistent as possible. 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 has completed the requirements for colour, glitter, silver silk, black dots and colours can reduce the number of false orders and facilitate the production, testing, installation and sale of the same version of data.
