Plastic mold grades are divided into five grades according to production volume, product accuracy, customer requirements and quotations: precision molds, mass production molds, medium production molds, small production molds, hand-made molds or test molds. 1,000,000 beer or above, precision mold.

1. A detailed mold structure diagram is required. 2. The hardness of the mold material is at least 28 HRC. 3. The inner mold steel with glue position must be pre-hardened to 48 ~ 50HRC. The other parts such as row position, pressure lock, pressure strip and so on should also be hardware. 4. The ejector pin plate must have a center bracket. 5. To install straight Body lock or oblique lock. 6. For all waterways, it is recommended to use electroless nickel or 420 stainless steel as a template. This can prevent rust and clean up the garbage. 7. The upper mold, lower mold and row position must be temperature controlled. 8 Abrasion-resistant blocks are required for row positions and pressure locks. Two. Beers larger than 500,000 and not more than 1,000,000, large-scale production of molds 1. Detailed mold structure diagrams are required. 2. Mould material hardness is at least 28 HRC 3. With rubber-positioned inner The steel of the module should be hard to a minimum of 48 ~ 52HRC, and the remaining parts such as row position, pressure lock, and bead should also be hardware. 4. It is recommended to use a straight lock or a diagonal lock. 5. The following items are recommended to use the following items when quoting To check whether you need A. The ejector plate should be in the middle of the company. B. The row position and pressure lock must have a wear-resistant block. C. Electroplating water hole. D. Electroplating mold cavity 3. More than 100,000 beer but not more than 500,000 beer, medium Mass production of molds. 1. Detailed mold structure diagram is required. 2. The minimum hardness of the mold material is 16HRC. 3. The inner mold steel is P20 (28 ~ 32HRC) or high hardness (36 ~ 38HRC). 4. The rest of the requirements depend on the needs. 4. For beer larger than 500 beer but not more than 100,000 beer, a small number of production molds 1. The mold structure drawing is required. 2. The mold material P20 (28 ~ 32HRC) can be made of mild steel or aluminum. 3. The inner mold can be made of aluminum, mild steel or other approved metal. 4. Other requirements are subject to need. 5. Less than 500 beer, hand-made molds or test molds can be cast aluminum or epoxy resin or any material as long as it has sufficient strength. A minimum number of tests can be produced.
