Key Types of Dowel Pins

Explore different dowel pin designs tailored for alignment, retention, and repeated use in precision assemblies:

Straight Dowel Pins: The most common form, ideal for general alignment applications in mold and die setups.
Stepped Dowel Pins / Step Dowel Pins: Designed with two different diameters for precise positioning and easy insertion; commonly used when alignment and retention need to be handled separately.
Ring Dowel / Dowel Rings: Feature a grooved or ringed profile for secure placement and improved grip in plastic and soft material applications.

Material and Tolerance Options

Although these plastic mold components typically work with steel dowels, MISUMI dowel pins are available in high-grade materials to support repeated use in high-temperature environments. Shaft diameter tolerances ensure a press-fit or slip-fit as needed, depending on the application requirement. These precise tolerances help reduce play and misalignment.

Tapped Variants

Some dowel pins feature a tapped hole, allowing for easy removal using a threaded extraction tool. These tapped-type dowel pins are especially useful in applications where frequent disassembly or maintenance is required, preventing damage to the mold base.

Typical Applications

Precise alignment of core and cavity in plastic injection molds
Registration of two halves of a mold to ensure proper fit
Locating features for inserts and replaceable components
Assembly of plastic fixtures and modular components
