Pad Urethane Blocks with Hole

Pad urethane blocks with a through hole are used in injection mold tooling wherever a compact, repeatable bearing or locating surface is needed. The through hole simplifies fastener-based positioning and supports repeatable setup when dies, carriers, or fixture elements are removed and reinstalled.

• Automotive and electronics connector molding setups: Use the urethane pad as a die or slide bearing and as a locator/stop to stabilize contact and control load transfer during frequent press cycles.
• Die attach and alignment fixtures: The hole enables pin or bolt alignment for consistent clamping locations, helping maintain fixture geometry during maintenance intervals.
• Forming and tooling work supports: Select the appropriate load-performance urethane type to tune compliance—lower load variants reduce deflection, while higher load variants improve support under heavier stamping/forming loads.

This variant’s through-hole layout and urethane pad shape make it well suited for stable positioning and controlled load distribution.

This component uses a selectable urethane load-performance type, allowing engineers to tune stiffness and damping without changing the tooling interface geometry. Available types include PO-652 Tan (Very high load), PO-670 Black (Very low load), PO-650 Red (Medium load), and CU-290 Yellow (High load).

• Wear/deflection trade-off: Higher-load urethane types are intended to provide stronger support with reduced sag under sustained contact, while very-low-load types provide greater compliance for fine positioning or shock absorption.
• Heat treatment and manufacturing: As a urethane pad system, performance relies on the molded/formed polyurethane chemistry and curing rather than steel heat treatment cycles. Final properties are established through the manufacturer’s polyurethane production and curing process.
• Material comparison: If your process is sensitive to pad compression, choose PO-670 Black; for heavier contact loads and higher rigidity, choose PO-652 Tan or CU-290 Yellow.

Select the block dimensions by matching the contact footprint and mounting hole location to the mold cavity/core or fixture interface. Confirm that the pad’s width parameters (A and B) fit within the available tooling envelope without interfering with adjacent tie-bar, ejector, or gate components.

• Length (L): Choose from 100, 415, 500, 835, or 1000 mm to match the required bearing/stop span along the die or fixture surface.
• Height (T): Available values are 25, 30, 45, or 50 mm; select based on allowable stack-up and deflection requirements.
• Planform widths: Use A options 110, 80, 75, 50, 30, or 25 mm and B options 45, 50, 30, or 25 mm to achieve the target contact area.

Because the hole enables repeatable mounting, ensure the mounting interface (bolt/pin clearances) is compatible with your fastener diameter and that the pad is constrained to prevent shear movement under cyclic loading. Dimensions are available as fixed catalog sizes rather than continuously configurable values.
