■ Features • It can release gas as well as air efficiently out of cavity from a groove (S). • Even if resin and tar gets clogged in the gas–release groove in part A of above drawing, it can be removed easily by taking out the insert from the mold. • Resistant to corrosion because it is made of stainless steel. ■ When using 1. Insert into a section where gas tends to accumulate, such as the final filling part. 2. Select an appropriate groove width (S) by resin liquidity and mold conditions. 3. Please be careful about mounting position because shape of the groove may appear on the surface of the finished product depending on the groove width and resin.
■ How to Mount 1. Make a reamer hole of depth L (tolerance of H7) at the parting line (P.L.) on the movable side of die plate. 2. Make a counterbore for fixing bolt in the backing plate. Perform air release processing on the counterbore. 3. Insert BGVS into the mold and fix it with a bolt. Use of spring washer is recommended to facilitate prevention of loosening.
