ALAS | Industrial Tooling & Wear Components: Engineered for Performance

We provide expert application engineering support, not just replacement blades. At ALAS, we help you optimize material selection, reduce downtime, and solve complex cutting challenges through advanced metallurgy.
We deliver reliable, field-proven tooling for metal shearing, rebar processing, recycling, and fabrication worldwide. Our focus is on consistent performance and the lowest total cost of ownership—delivering the science behind every edge.

Our Engineering-Driven Advantages

 

Consistent Hardness & Quality You Can Measure

Through our structured hardness testing and flatness control, we minimize uneven wear, chipping, and premature failure. Every blade is built for stable, repeatable performance in real production environments.

 

Materials Engineered for Actual Wear Modes

We select and optimize tool steel alloys (H13, D2, DC53, SKD-11, LD) to match specific abrasion, impact, and fatigue conditions. Your tools last longer, require fewer regrinds, and minimize unplanned downtime.

 

In-House Precision Manufacturing

Full in-house CNC machining and grinding ensure tight dimensional accuracy, proper fit, and batch-to-batch consistency without reliance on outsourced general processing.

 

Application Support Before & After Sale

We provide specification guidance, setup parameters, and troubleshooting. Our goal is to ensure your tooling performs perfectly on your specific machine from day one.

 

Core Tooling Solutions

 

Shear Blades & Cutting Knives

For plate shears, scrap shears, alligator shears, and stainless steel processing. Built for durability and clean cutting.
 

Rebar & Construction Tooling

Rebar cutter blades, bending dies, upsetting tools, and accessories for high-volume concrete reinforcement production.

 

Press Brake Tooling

Standard and custom punches, dies, and segments for accurate, consistent bending across a range of sheet thicknesses.
 

Shredder & Crusher Blades

For metal, plastic, wood, and waste recycling systems optimized for toughness, wear resistance, and high throughput.
 

Custom & Special Tooling

Fully custom blades, dies, and wear parts based on your drawing, application, or machine specification.
