Precision Mold Components are the general terms for small pieces of mold parts. These precision mold parts are used in stamping punching molds, plastic injection molds, automatic system machines, or fixture parts.
Precision mold parts accessories include: cutting punch, punch and die set, core and cavity set, ejector pins and ejector sleeves, guide pins and guide bushings, thimbles and barrels, mold inserts, mold locks cylinder parts, square and rectangle parts, special-shape parts, Automaton Precision Components, fixture components, custom mold parts, and other standard mold parts.
There can be categorized into three main types:
- hardware stamping die punching components
- plastic mold precision parts
- non-standard automation system, assembly machine, and fixture precision components.
According to the application, there are precision mold parts for the auto car industry; precision mold punches for electronics mobile and computer industries; precision mold components for the medical industry; precision elements for terminal assembly; precision components for automatic system machines and fixtures, etc.
There are also some mold components that are used in very specific industries. For example, the LED industry, Unmanned Aerial Vehicle(Drone) Industry, and Aerospace Industry, etc.
The Mold Components also can be called mold inserts. There are standard mold parts and special-shaped mold parts (or called custom mold parts). They are embedded in the mold, playing the role of fixing the space between the template and filling the template. The mold inserts can be square, round, sheet-shaped, and special-shaped. their precision requirements usually are extremely high. Generally, there is no finished or standard product, each mold component and insert needs to be customized according to the needs of the mold.
Most of them are used as tiny precision parts inserted into a big mold. precision mold parts have the function of exhaust, easy processing, easy to replace, and easy to control important sizes.
Let’s see some of the commonly used precision mold parts in different kinds of mold below:
1 Hardware stamping die components & punching parts:
|Punches and dies||type straight punch, A-type secondary punch, edge forming punch, K-type budding punch, B-type guide punch, A-type sub-female punch; high-speed steel round bar, ultrafine particle tungsten steel round bar, powder high-speed steel round bar.|
|Ejector pin and ejector sleeves||float pin, dowel pin (fixed pin), Eq-heigh sleeve.|
|Guide pin (guide post) and guide bushing||precision grade chrome guide post, precision grade copper titanium alloy guide bushing, self-lubricating guide bushings, inner guide post assembly, sliding guide post assembly for mold base, ball guide post assembly for mold base, detachable ball guide post assembly, outer guide post assembly, steel ball bushing (cage), independent guide post.|
|Screws||hexagonal screw, contour screw, stop screws,etc.|
2 Plastic Injection Precision Mold Parts

|Other Parts||Square type assist, stereotactic block group guide position assist, A B C nozzle, fixing ring A B type, tie rod, small tie rod C type, standard type mechanical switch, square type assist, mold date indicator device, resin switch, water stop, spring, garbage nail, etc.|
3 Automation System Precision Parts
Guide shaft supports, fixing rings, linear bearings, ball guide shafts, oil-free bushings, linear guides, ball screw support assemblies, trapezoidal lead screws, sliding lead screws, rotating shafts, bearing housings and bearings, cantilever pins, hinge pins, step screws for fulcrums, couplings and motors, synchronous pulleys and idlers, keyless bushings, pulleys, idlers, conveyor parts, gears, conveyors, bushings for locating pins and fixtures, positioning parts, probes, struts, supports, pillar fixing clamps, toggle clamps, and washers Shaft rings, gaskets, screws, washers, nuts, handles, handwheels, knobs, handles, hinges, door parts, angles, sections, corners, stiffeners.
Although these precision mold parts are small and tiny, they are essential. And Because of ultra-high precision dimension requirements, they are not easy to make. There is why the ultra-high-precision mold components machining industry exists.
