: If the flow distance is long, there need to be a multipoint gate. In this case, attention against weld location is required. If the width of the molded product is large, setting up the multipoint pin gate on the centerline is good.

（1） Long and thin will be greatly affected by the gate design, and it should be a design that resin flows towards

longitudinal direction. If the flow distance is short, the end gate from one end will be suitable to prevent

deformation.
