1. For the mold blank smaller than 2020, a pry pit is needed between the A and B plates; All templates of molds larger than 2020, including thimble plates, should be pried into mold pits.
2. The exhaust groove should be processed for the guide sleeve of the mold blank to prevent the guide sleeve from being pulled.
3. There must be no sharp corners on the mold, and chamfering is required. Except where specified.
4. Internal mold and mold parts shall not be welded without consent.
5. The periphery of the mold product must be provided with an exhaust groove at an appropriate position. Please refer to the mold design manual for the specifications of the exhaust groove.

7. The surface treatment of internal mold glue plane must be carried out according to bom or other officially notified technical requirements. The machining lines (wire cutting, milling machine, cnc gong bed, spark machine) on the non-adhesive plane should also be lightened with oilstone.

10. row position, push block, shovel chicken, pump mouth and other important wear parts must be nitrided and hardened.
11. Line position must be positioned. Positioning methods include slingshot, wave beads, hasco(dme) standard line clamp, etc., depending on the requirements of each project. Line need to have layering, wear-resistant plate. Wear-resistant hard materials must be used for layering and wear-resistant plates, and oil grooves need to be added.
12. The inclined guide pillar must be pressed tightly, and cannot rotate or loosen. The tail of the inclined guide pillar must be machined into a hemispherical shape or a truncated cone shape, which is conducive to ensuring the normal movement of the row position. If there are two or more inclined guide posts in the same row, the length, size and inclination of the inclined guide posts must be the same.
