PWB Type Punch Spacers and Shims for Height Adjustment

PWB type spacers and shims are used inside headed punch machining setups to establish a stable, repeatable punch working height. During tool building or cavity punch assembly, these parts help set the correct punch spacing so punch alignment is maintained across the stack.

• Automotive connector and bracket stamp tooling: In progressions where multiple punches must act at consistent stroke height, a shim stack supports tight height control and reduces variation between machining steps.
• Electronic part transfer/blanking dies: When fine adjustment is needed to match punch wear or to correct spacing after rework, thickness options allow incremental setup changes without replacing the entire punch holder.
• General headed punch systems: The PWB configuration is suited for consistent positioning in MISUMI headed punch arrangements, improving assembly repeatability for smoother production runs.

By selecting the appropriate outer diameter and thickness combination, designers can tune height adjustment while keeping the spacer/shim interface stable during machining and assembly.

These PWB type punch spacers and shims are component spacers used to stabilize punch working height during headed punch machining. The available specifications provided for this item focus on geometric fit (D and T), and no specific steel grade, heat treatment condition, or target hardness (HRC) is stated in the supplied data.

Because no material grade is included, selecting the correct variant should prioritize dimensional compatibility with the corresponding headed punch system and maintaining the intended stack-up thickness. In general practice for punch spacer applications, higher hardness materials improve wear resistance but can reduce toughness if misapplied; however, this trade-off cannot be confirmed for this specific SKU from the provided information.

• Material / heat treatment: Not specified in the supplied metadata.
• Hardness (HRC): Not specified in the supplied metadata.

For heat-treatment and hardness requirements, verify with the manufacturer documentation for series code 110100101420.

To select the correct spacer/shim size, match two dimensions from your tool stack-up: the outer diameter (D) and the thickness (T). For this series, D is 5 ~ 28 mm, and T is 0.5 ~ 5 mm with available ranges of 0.5 to 5 and 1 to 5.

• Match outer diameter (D): Choose the D value that fits the surrounding punch/holder interface clearance and ensures stable seating in the headed punch setup.
• Match thickness (T): Select thickness to achieve the required height adjustment. Use a shim stack strategy when fine increments are needed within the available T options.

Tolerance & fit: While no tolerance values are provided in the data, accurate height control depends on using the correct D for proper centering and selecting T that corresponds to your target stack thickness. Confirm the total assembled thickness against the mold’s required punch working height before finalizing machining.

All dimensions in this series are configured by choosing the appropriate D and T; other dimensions are not listed as adjustable in the provided specifications.
