Each Zamboni®-compatible blade is crafted at SHJ KNIFE's ISO-certified facility with strict process control from start to finish. Our precision manufacturing ensures consistent quality with every blade:

 

 

--Material Preparation & Blanking

We begin with high-carbon or alloy steel, selected for its toughness. Steel sheets are cut into precise blanks using industrial shearing and rolling techniques.

 

--Rolling & Coarse Grinding

The blanks are then rolled to the desired thickness and surface-ground to remove excess material while maintaining flatness.

 

--Straightening for Dimensional Accuracy

Our technicians perform mechanical straightening to eliminate warping and ensure uniform blade geometry.

 

--Heat Treatment for Hardness

Blades undergo a controlled heat treatment cycle to optimize hardness and durability, essential for extended ice resurfacing performance.

 

--Drilling & Final Sharpening

Mounting holes are drilled with CNC accuracy. The edges are then sharpened using fine grinding to achieve a clean, consistent cutting surface.

 

 

 

To ensure each blade delivers peak performance on the ice, SHJ KNIFE enforces a strict quality control process at every production stage.

Our ISO-certified facility follows globally recognized quality protocols. Technicians perform optical comparator measurements to confirm dimensional accuracy and mounting compatibility across resurfacing machine types.

We conduct Rockwell hardness tests (HRC 60–62) on every batch to verify the blades meet the ideal balance of edge retention and structural toughness.

In addition, we simulate ice resurfacing pressure through load testing, helping us detect any micro-defects or inconsistencies before blades leave the factory.

Every blade is individually inspected-no random sampling. This ensures customers receive only consistent, ready-to-install scraper blades built for demanding rink environments.

 

 

We know your blades need to arrive in perfect condition-sharp, clean, and ready for action. That's why we take packaging and shipping seriously.

 

Each ice scraper blade is carefully wrapped in protective sleeves to guard the edges, with anti-rust film added for moisture protection when needed. For bulk orders, we pack everything in sturdy wooden crates or heavy-duty cartons that can handle long-distance transport.

 

All of our export packaging meets international shipping standards, so you don't have to worry about customs delays or repacking issues. We work with reliable global carriers to ship worldwide by sea or air. Whether you're managing a rink in the U.S., Europe, or Asia, we'll make sure your order gets to you safely and on time.

 

 

 

Need specific labels, barcodes, or pallet sizes? Just let us know-we're happy to customize the packing to fit your warehouse needs.

 

 

 

 

We know that every rink has its own needs. That's why we offer OEM and customization services to help you get the exact ice scraper blades you need. Need a specific size, unique hole patterns, or a different edge shape? We can customize the blades to match your resurfacing machines perfectly. We're happy to work with you to get the fit just right.

 

 

Looking for additional features like anti-corrosion coatings or even a special color to match your rink's branding? We can do that too. Whether it's a small order or a large production run, we're ready to create high-quality blades that meet your exact requirements. And no matter what customization you choose, all our blades are built to last and perform just like our standard models.
