Precision Press Brake Tooling Dispatch: Quality Control, Heat Treatment & Selection Guide

Introduction 

Recently, JSTMT completed and dispatched a custom shipment of high-precision press brake punches and dies for international sheet metal fabrication clients. Quality tooling is essential for maintaining consistent bend angles, preventing springback errors, and extending machine operational life.

Section 1: Material Selection & Heat Treatment Standard

When selecting press brake tooling for heavy-duty bending, material integrity directly dictates wear resistance and tool deformation limits.

Primary Material (42CrMo / 42CrMo4): High-tensile alloy steel providing exceptional toughness under continuous high-tonnage loads.

Hardening Process: Whole-body heat treatment combined with high-frequency induction hardening along working edges, achieving 47 ± 2 HRC surface hardness.

Wear Resistance: Engineered for processing high-tensile stainless steel, carbon steel, and galvanized sheet metal with minimal edge degradation.

Section 2: Precision Manufacturing & Quality Inspection Log

Before dispatching any tooling set, JSTMT executes a 3-step quality verification process:

Ultrasonic Defect Testing: Inspection of raw forging blocks to rule out internal cracks or air pockets.

CNC Precision Surface Grinding: Clamping grooves and working radii are ground to a precision tolerance within ±0.01mm, allowing seamless sectional tool interchangeability.

Hardness & Angle Verification: Laser-guided angle checks and digital hardness testing across all segments.

Section 3: Export Packaging & Rust Prevention 

To ensure tooling arrives in factory-fresh condition without oxidation during long-distance ocean or air freight:

Anti-Rust Oil Coating: Heavy protective oil film applied to all ground surfaces.

VCI Moisture Barrier: Wrapped in Volatile Corrosion Inhibitor (VCI) vacuum packaging.

Plywood Crates: Reinforced fumigation-free wooden packaging anchored with heavy-duty steel strapping.

FAQ  Questions

Why is 42CrMo steel preferred for press brake tooling?

42CrMo is a high-strength alloy steel offering an excellent balance of toughness and wear resistance. When heat-treated to 47±2 HRC, it resists cracking and plastic deformation under high bending forces

 

How does JSTMT protect press brake tooling from rust during ocean freight

All Press brake tooling undergoes anti-rust oil coating, vacuum VCI moisture-proof film wrapping, and is packed in heavy-duty fumigation-free wooden crates before container loading.
