punch holder insert

Our Mold & Die Tool Inserts deliver modular, high-precision components that slot into larger mold bases and stamping dies for fast changeover, improved uptime, and cost-effective maintenance. Manufactured to LKM standards with tolerance down to ±0.05 mm, these inserts support complex tooling layouts—from punch holders and sliders to core-and-cavity sections—across injection, compression, and progressive stamping applications.

Materials & Standards

• Mold Steel Grades: P20 (1.2311), H13 (1.2344), S7 (1.2357), 420 (1.2083), NAK80 (P21), S136 (1.2083)

• Standard Compliance: LKM mold-base specifications

• Dimensional Tolerance: ±0.05 mm

• Surface Finish: Polished or textured per design

Insert Types

• Punch Holder Insert: Precisely locates and supports punch elements, ensuring repeatable strike angles and minimal deflection.

• Lower Plate Insert: Custom-machined bottom inserts that register with ejector systems and maintain consistent part ejection.

• Slider Insert: Integral side-core slides with anti-friction channels and hardened guide surfaces for wear resistance.

• Core & Cavity Insert: High-tolerance cavities and core cores for complex geometries, undercuts, and multi-color molding.

• Stamp Punch Insert: Replaceable punching heads for blanking, piercing, and forming operations in progressive dies.

Key Advantages

Enhanced Precision

• Ultra-tight tolerances and advanced CNC grinding ensure exact fit and uniform part quality.

Cost-Effective Maintenance

• Replace individual inserts instead of entire mold blocks, reducing downtime and tooling investment.

Flexibility & Customization

• Mix-and-match insert materials, coatings, and geometries to suit diverse production requirements.

Improved Productivity

• Pre-machined inserts allow rapid tool trials and quick changeover, boosting press uptime.

Reduced Lead Time

• Standardized insert footprints enable faster quoting, machining, and stock-on-shelf readiness.

Increased Durability

• Hardened and polished steels resist wear, thermal fatigue, and corrosion under high-stress cycles.

Typical Applications

• Plastic Injection Molding: Multi-cavity molds, hot-runner systems, and insert-injection processes.

• Progressive Stamping Dies: High-speed blanking, piercing, forming, and deep-drawing operations.

• Compression & Transfer Molding: Replaceable die faces and inserts for elastomer and thermoset parts.

• Medical & Electronics: Precision cores and cavities for tight-tolerance components.

Quality & Service

• Full DFM Review and 3D Verification before machining

• In-house CNC machining, wire EDM, and surface treatments

• Complete inspection reports (CMM data) with each delivery

• Engineering support for insert interchangeability and modular layouts
