As a professional dry die production enterprise, Yixing Hongguang Mould Factory provides various standard size material pressing molds. Moreover, the outer surface material of the mold is made of stainless steel, which has good anti-rust performance; the mold sleeve, the backing plate and the core material of the mold adopt the quenching hardness mold steel, which has good wear resistance and pressure resistance characteristics.
There are many different types of dry stamping die, including open dry die, closed dry die, semi-closed dry die, hinged dry die, and external hoop compression dry press. mold. Each mold has its own characteristics, so it is suitable for the suppression of different products.
In the case of an open dry die, it is mainly used to press the product when the upper and lower dies are pressed, and the excess rubber is overflowed and has a horizontal burr, so it is suitable for low hardness and large flow. Squeeze of rubber and simple rubber products.
The closed dry die is just the opposite. The upper end of the cavity of the mold has a certain degree of mold fit, so that the rubber does not easily overflow during the pressing process, and can fully fill the cavity, ensuring that the finished product is compact and reduces the product. The possibility of a defect.
There is also a semi-closed dry die between the closed type and the open type. The mold is characterized in that it has a certain depth of tapered surface at one end, so it is safe to operate, reliable in positioning and difficult to pull the mating surface, suitable for upper and lower belts. There is a cavity and a single cavity mold with high coaxiality requirements for rubber products.
The remaining hinged and outer hoop compression dry die are not common at ordinary times. The former is suitable for small rubber parts or the inserts in the mold are exposed on the punch and easy to touch during operation; the latter is suitable Pressing of cloth and other fabrics such as cloth tape and flat tape.
Since the dry stamper of different structures has different characteristics and application range, the user must select the material, characteristics, structure and requirements of the product when selecting the dry stamping product.
