Thermoforming processing selects appropriate sheets and molds according to the requirements of the preparation and construction instructions.

　　1) Accept and clean and lubricate the relevant thermoforming molds.

　　2) Obtain relevant sheets and pre-press check materials, external dimensions, thickness, and weight (quantity).

　　Thermoforming mold installation—Install the relevant molds, check the air intake preheating and vacuum pump suction. After preheating to the specified temperature, adjust the product to the requirements of the construction drawing document.

　　Thermoforming molding production—Install the sheet on the plastic suction device and carry out normal production (softening, plastic, molding). The heating, softening, vacuum plastic molding takes 3 seconds, and the cooling of defective products takes 12 seconds. Stack the intermediate products in the designated location. Conduct semi-finished product quality inspection according to the construction table.

　　Semi-finished product stamping—Install and debug the applicable stamping mold, stamp the qualified semi-finished products, put the defective products into the designated basket, and when stacking finished products, ensure the products are clean and undamaged. Conduct finished product quality inspection according to the construction instructions.

　　Thermoforming finished product packaging—Package according to the box, moisture-proof and dust-proof box lining, and construction order specifications, packaging in quantities per box. Fill in the proof documents (project description, specifications, weight, grade, batch number, roll number, class, date).

　　Product receipt—Receipt of the total quantity specified in the construction order.

　　Mold removal—First cut off the power, remove the entire mold, and clean and apply anti-rust agent until the plastic suction heater is completely cooled. Inspect and store after ensuring there are no defects, and keep good mold lead records.

　　Cleaning and sanitation—Maintain the cleanliness of the equipment for 4 weeks during production, carefully prepare production records, and complete the handover work. Organize the production content, quality requirements, and product stacking locations of the shift one minute in advance.
