Industrial components, explained and quoted
Plain-language engineering guides to the components JIDOKA supplies — what they are, the types, how to select them, and how to get them quoted.
MDMould & Die Components
View familyEjector Pins
Ejector pins push the finished part off the core when a plastic mould or die opens. They cycle millions of times against heat and friction, so material, hardness and fit decide tool life.
Guide & quotePunches
Punches do the cutting and forming in press tools. Edge life, shank accuracy and coating decide how many strokes a tool runs between regrinds.
Guide & quoteButton Dies
Button dies are the hardened female counterparts to punches — the slug passes through them each stroke. Correct clearance and land geometry control burr height and edge life.
Guide & quoteLocating Pins
Locating pins fix a workpiece in a repeatable position on a jig or fixture. The round-plus-diamond pair is the standard method of constraining a part without over-constraint.
Guide & quoteLeader Pins
Leader pins keep the two halves of a die set or mould base aligned through every stroke. Alignment accuracy here protects punches, cavities and product quality.
Guide & quoteGuide Pins & Guide Bushes
Guide pins and bushes align mould halves at every close. They are the first components to feel misalignment — and the cheapest place to fix it.
Guide & quoteMould Cooling Components
Cooling decides cycle time. Baffles, plugs and nipples route water through the mould so every cavity region holds the right temperature.
Guide & quoteEjector Sleeves
Where a boss must be ejected around its core pin, only a sleeve can push evenly on the ring of plastic — the ejector sleeve is that part.
Guide & quoteGuide Post Sets
Guide post sets are the alignment system of a press die — post, bush and (optionally) ball cage supplied as a matched assembly.
Guide & quoteCore Pins
Core pins form the holes and bosses in a moulded part — precision pins that live inside the cavity, cycling with every shot.
Guide & quoteSPSprings & Force Components
View familyCoil Springs
Coil springs return plates, strip parts and hold pressure in tools and machines. Standardised load classes make replacement fast — if you match the class correctly.
Guide & quoteDie Springs
Die springs pack maximum force into a standard hole — rectangular wire and controlled stress make them the force standard in press tools.
Guide & quoteGas Springs
Gas springs deliver full force from the very start of the stroke — something no mechanical spring can do — which is why modern forming dies rely on them.
Guide & quoteShock Absorbers & Dampers
Every moving axis has to stop. Shock absorbers turn that stop from a bang into a controlled deceleration — protecting product, machine and cycle time.
Guide & quoteLMLinear Motion & Bearings
View familyOil-Free Bushings
Oil-free bushings run without lubrication lines — solid lubricant embedded in the bearing wall feeds the sliding surface continuously.
Guide & quoteLinear Shafts
The shaft is half of every linear bushing system — its hardness, roundness and surface finish set the accuracy and life of the motion.
Guide & quoteLinear Bearings
Linear bearings put recirculating balls between shaft and carriage, turning sliding friction into smooth rolling motion.
Guide & quoteLinear Guide Rails
Profile rail guides carry heavy, offset loads with high rigidity — the standard motion element of machine tools and automation axes.
Guide & quotePFProfile, Frame & Structural
View familyPTPower Transmission
View familyTiming Belts & Pulleys
Timing belts transmit torque tooth-by-tooth — no slip, no lubrication — making them the default for positioning drives and clean power transmission.
Guide & quoteChain & Sprockets
Chain drives move serious torque over long centre distances and rough conditions — the muscle of conveyors and heavy machine drives.
Guide & quoteShaft Couplings
A coupling forgives what machining can't: the small misalignments between motor and shaft that would otherwise destroy bearings.
Guide & quoteMSMachine Standard Components
View familyO-Rings & Seals
Every mould water line, cylinder and gearbox depends on seals. Standard O-ring sizes and the right elastomer keep them dry.
Guide & quotePlungers
Plungers give machines a sense of position — the click of a detent, the hold of a spring-loaded ball, the lock of an index pin.
Guide & quoteShoulder Bolts & Stripper Bolts
A shoulder bolt is a bearing surface, a guide and a fastener in one part — and in press tools, the stripper bolt version carries the stripper plate itself.
Guide & quoteWashers & Shims
Millimetres are set with washers and shims — the small parts that give an assembly its exact heights, gaps and preloads.
