Type	Characteristics	Shape	Part Number	Example
For straight, no tapering required	The bushing is tapered and facilitates processing plates.		RLBST
For straight	Guide for straight runner lock pin		RLBS
For tapered	Guide for tapered runner lock pin		RLBT

Type		Characteristics	Shape	Part Number		Example
				L dimension selection	L dimension designation
For movable side	For ejector pin	The runner change pin itself has a sprue lock function. Use it together with the ejector pin with tip shape processing.		RCPN	RCPL
	For Z pin assembling	Sprue lock function by using a Z pin. (Ejector pin with Z groove) Click here		RCPNZ	RCPLZ
	Flow quantity adjustable	By using this type together with a stopper, fine adjustment of the runner flow rate can be performed from the PL face.		RFAN	RFAL
Fixed side type		Type used without combining ejector pin. For fixed side.		RCPK	-
