A pin gate bush incorporated in an injection mold is located at the edge of a resin passage. With its taper pin-shape, it cuts off automatically when being molded. The problem for customers is that it causes whisker-like leftovers on products from the gate. This company has developed an original-shaped pin gate bush as their first own product; they adopted a flat-shaped edge instead of traditional perfectly circular-shape, so that resin can be solidified quicker and gate leftovers are consistently smaller.
