(1) The loss of raw materials is small and will not cause excessive loss (usually 2% to 5% of the product quality).
(2) The internal stress of the product is very low, and the bending deformation is also very small, with relatively stable mechanical properties.
 
(3) The wear of the mold cavity is minimal, and the maintenance cost of the mold is relatively low.
 
(4) The cost of molding equipment is lower, its mold structure is simpler, and the manufacturing cost is generally lower than that of injection molds or transfer molding molds.
 
(5) Can form larger flat products. The size of the products that can be molded by compression molding is only determined by the clamping force of the existing compression molding machine and the template size.
 
(6) The shrinkage rate of the product is small and the repeatability is good.
 
(7) It is possible to place a large number of mold cavities on a given template, resulting in a high production rate.
 
(9) Be able to get used to actively adding ingredients and taking out products.
 
(10) High production efficiency, easy to achieve specialized and proactive production.
 
(11) The product has high precision in scale and good repeatability.
 
(12) The surface is smooth and does not require secondary polishing.
 
(13) Can produce products with a disordered structure in one go.
 
(14) Mass production, relatively low price
