1: Mold installation

1. Place the material tube horizontally (front, back, left, right, top, and bottom), adjust the height of the center to the appropriate size, and then tighten the car screws and nuts.

2. The material tube usually needs to be removed from the cast-in-place plate and the side plate pad before heating (to facilitate the final tightening of the large screws of the plate before starting work).

3. Before heating the material tube, remove the 6 screws connecting the flange and the lower mold, and the flange and the upper mold connection screws will not be removed (to facilitate the large screws of the plate to be clamped before the final start).

2: Heating and insulation

4. The temperature of the barrel and the barrel heating zone is usually set at 150℃---130℃ for heating, and then heated after 2 hours of insulation. Barrel temperature setting: 1st barrel 171°C, 2nd barrel 162°C, 3rd barrel 165°C, 4th barrel 155°C, 5th barrel 130°C, confluence core 146°C (barrel temperature is usually based on the raw material smelting layer. The temperature should be lowered for good smelting and relatively increased for poor smelting)

5. Material tube temperature setting (the standard is that the temperature on both sides of the material tube is slightly higher and the temperature in the middle is slightly lower). Mold temperature reference is given:

6. Area 1 Area 2 Area 3 Area 4 Area 5 Area 6 Area 7 Area (Area 8-Area 9 is the side plate)

7. 171℃ 166℃ 163℃ 165℃ 163℃ 166℃ 171℃ 174℃ 174℃

8. Water temperature is generally 160-162℃ (actually depends on the polyurethane foaming and feeding conditions of the board).

9. After the material tube rises to high temperature, the large screws of the plate can be clamped, and then the flange screws can be fixed. Adjust the parallel plane and balance of the barrel and the setting table together, adjust the mold gap according to the specifications of the crafts, and then clamp the cast-in-place plate and side plate pads.

Three: Die spacing and fixed mold adjustment

10. Under normal circumstances, the mold gap adjustment ratio is 1:5. For example, for a craft with a thickness of 15mm, the mold gap is usually adjusted to 3mm. And the upper and lower sides of the opposite sides in the middle should be slightly less than 0.3-0.4mm. (The adjustment tool is a copper feeler gauge).

12. The final length-to-width ratio of each section of the setting mold (each section farther away from the material tube) is usually the same as the thickness of the craft (can be slightly less than 0.1-0.3mm). The third section becomes larger to 0.6mm, and so on.

12. Most of the preliminary preparations can be started. Before starting, add some paraffin wax to the barrel observation hole to keep the extruder screw and barrel lubricated.
