Send a drawing, a sketch with the bore angle and pin size, or a photo of the existing block, and we quote in writing, normally within one business day.\u003c\/p\u003e\u003ch2\u003eWhat this block has to stop the pin doing\u003c\/h2\u003e\u003cp\u003eAn angle pin is loaded sideways on every cycle. Three failure modes follow from that, and the fixing block exists to prevent all three:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotation.\u003c\/strong\u003e A pin that turns in its seat wears a spiral into the bore and loses its ground surface. Once it is turning, the bore is finished. Clamping has to grip the pin's full seated diameter, not pinch it at one point.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAxial creep.\u003c\/strong\u003e A pin that walks out even half a millimetre changes the engagement length — and engagement is what stops the slide over-travelling. Pins creep out, not in, because the reaction on mold-open pushes them that way.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFretting at the clamp face.\u003c\/strong\u003e If the clamp is not tight enough to prevent micro-movement but tight enough to load the surface, you get fretting: a red-brown powder at the joint and a bore that grows. Either clamp properly or use a keyed retention feature.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eThe bore angle has to match the pin, not approximately\u003c\/h2\u003e\u003cp\u003eThe bore in the block and the working angle of the pin must be the same figure. If the block is bored a degree off, the pin seats on a line contact instead of over its full length, and that line is where it will bend. This is the single most common reason a replacement block does not fix the problem it was bought for.\u003c\/p\u003e\u003cp\u003eSo when you send dimensions, give the bore angle explicitly rather than letting us infer it from the pin — and if you are replacing a block on a mold that has been running, it is worth measuring the pin's actual angle rather than trusting the original drawing.\u003c\/p\u003e\u003ch2\u003eHardness: the block should not be as hard as the pin\u003c\/h2\u003e\u003cp\u003eA through-hardened pin running in a similarly hardened bore galls. Normal practice is a hard pin in a block that is deliberately softer and cheaper to remake, or a hardened block with a replaceable bushed bore. Decide which part you want to replace, and that decision sets the pair.\u003c\/p\u003e\u003ch2\u003eWhat to send us\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBlock length, width and height\u003c\/li\u003e\n\u003cli\u003eAngle-pin bore diameter and bore angle\u003c\/li\u003e\n\u003cli\u003eMounting-hole, counterbore and thread layout, and centre distances\u003c\/li\u003e\n\u003cli\u003eMounting orientation — which face is the datum against the plate\u003c\/li\u003e\n\u003cli\u003eAngle pin diameter, length and how it is currently retained\u003c\/li\u003e\n\u003cli\u003eMaterial, hardness and tolerance; quantity and destination\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eReplacing one that failed?
