The problem with many PC Translucency Projects is not the lack of equipment capacity, but the omission of high temperature, viscosity, water content and transparency deficiencies from the selection phase. The ability of optical and household electric equipment suppliers to complete technical confirmation prior to the offer would significantly reduce the risk of subsequent re-engineering and complaints.

The name of the raw material can only be classified as the first layer, and what really determines the screw configuration is the viscosity, melting point, thermal stability, humidity, filling and additive of the specific plate. Vendors should obtain material forms and identify whether the customer uses raw, retroactive or retroactive formulations to discuss generic, grinding, corrosive or lower shear structures. 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.

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. The focus of discussion in this paper is on the deficiencies of high temperature, viscosity, water content and transparency, which must correspond to the current production conditions of the client and not be limited to the maximum values in machine samples.

The project advance may select the low front end of the hold, the grinding surface and a reasonable diameter as the main line, and 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.

If the above-mentioned steps are ignored, the most common consequence is a yellow-and-black spot due to a dead end and a long stay. The problems are often manifested in the trial phase of measuring time instability, insufficient stress residuals, buffer drift, unmelted, black spots, colour differentials or increased wear and tear. Continued increase in temperature, back pressure and turn speed at this time may temporarily improve the appearance, but may increase the shearing heat, material degradation and equipment load.

It is recommended that clients set clear upper and lower limits around the light look, the yellow index and the black dot, instead of simply writing “normally functioning”. 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. With the continued accumulation of project data on PC Transparents, the equipment manufacturer could gradually establish a package, a trade charter and an aircraft-type menu to allow sales to quickly identify general and special conditions, while also placing a truly complex project under the timely review of application engineers.
