1. You go and measure the size of the mold and check the opening with an injection molding machine. First, you must ensure that there is no problem in opening and closing the mold. The opening of 300-ton injection molding machines from different manufacturers is different. Check it yourself. Maybe your mold is 250t small, maybe 500t t.

2. The tonnage t of injection molding machine refers to the maximum force of mold locking to ensure mold locking.

3.800 g products need a lot of injection molding machine glue. If a small-tonnage injection molding machine is used, the amount of glue injected per unit time is small and it takes a long injection time. After a long time, it will cause many shortcomings of the product, such as glue line defects. Of course, your product's appearance function is not high, and it is a product with individual expression. In addition, considering the size of your product, the rubber road ratio is longer and the injection pressure ratio is larger.

Small tonnage machines may not meet the requirements, and if the mold has hot runner, the requirements for injection molding machines may be lower.

4. It depends on what material you use for this product, and what material you use for the same product also needs the tonnage of injection molding machine, generally it should be pp material. It is estimated that 300t is not enough

According to our production experience, it is estimated that we need 500-600 tons injection molding machine.

6, save costs (electricity, etc. ) Try to be close to the small machine, use the small machine if you can, and never use the big machine. But only if the small machine can complete the injection molding.

7. Regarding the purchase of injection molding machines, I believe that buying injection molding machines is not only for a product, but also for a long-term plan. Just buy a general injection molding machine for your current product. If most of the products you make are not demanding, buy ordinary ones. If most of your products are high-precision products, such as automobile exterior parts, it is recommended to buy a better injection molding machine. It's hard to say what brand it is, and we won't advertise to the manufacturers. Lest netizens splash me.
