Industrial Blade Solutions by Industry and Process

Why Choose Us

Why OEMs and Industrial Buyers Choose Yishi

Working with a dedicated industrial blade manufacturer means faster technical communication, more consistent product quality, and supply that fits your production schedule.

  • Blade Design Based on Cutting Conditions

    We recommend blade geometry, material, and hardness based on your substrate, thickness, line speed, and wear mode.

  • Stable Quality for Repeat Orders

    Controlled machining, heat treatment, and grinding help maintain dimensional consistency and repeatable edge quality across batches.

  • Support from Trial Order to Volume Supply

    From sample-based development to repeat production and export packing, we support both small-batch validation and long-term supply.

Industrial Cutting Solutions for Packaging, Recycling and Converting

From high-speed film slitting to heavy-duty shredding, we supply blade solutions matched to material type, machine setup, line speed, and required edge finish. Share your application details with our team, and we will recommend the blade geometry, material, and hardness needed to improve uptime and cutting consistency.

Highlights

  • OEM and custom blade manufacturing for industrial equipment
  • Tool steel and carbide options for wear resistance and edge stability
  • Precision grinding for repeatable dimensions and edge finish
  • Trial orders available before repeat production
  • Export packing and global shipment support

From Drawing or Sample to Finished Machine Knives

Our process is designed to reduce back-and-forth and help you move from concept to production-ready blades more efficiently.

Step 1 — Application Review

Share your machine type, material, thickness, cutting method, and target performance. We confirm the key requirements before production begins.

Step 2 — Blade Design Recommendation

We recommend blade geometry, material, and hardness based on wear conditions, cutting quality targets, and service life expectations.

Step 3 — Precision Manufacturing

Machining, heat treatment, and grinding are controlled to achieve dimensional accuracy, stable hardness, and reliable edge quality.

Step 4 — Inspection and Validation

We check key dimensions, edge condition, and overall consistency, with trial support available when required.

Step 5 — Packing and Shipment

Blades are packed for export to protect edges and surfaces, with documentation support for international orders.

How Industrial Blades Are Manufactured

Every blade we supply goes through a controlled production sequence — from raw material verification to final edge inspection. Here is how blade manufacturing works at Yishi:

  • Raw Material Verification

    We source tool steel grades (D2, SKD11, H13, M2) and tungsten carbide suited to each cutting application. Incoming stock is verified by spectrometry before entering the production queue. Blanks are cut to dimensions that account for heat treatment allowances and minimize machining waste.

  • Rough Machining

    Blanks are rough-machined to near-net shape on CNC milling and turning centers. Blade geometry, mounting features, and bore or slot dimensions are established at this stage, with allowances maintained for dimensional changes during heat treatment.

  • Vacuum Heat Treatment

    Tool steel blades are heat-treated in vacuum furnaces to reach target hardness — typically HRC 58–62 for D2 and SKD11 — while minimizing surface oxidation and distortion. Rockwell hardness is verified at multiple positions per batch to confirm consistency before grinding begins.

  • CNC Precision Grinding

    After heat treatment, blades are finish-ground on CNC surface and cylindrical grinders. Thickness, flatness, outer diameter, and bore are brought to final dimensional tolerance. Edge geometry — bevel angle, honing, and micro-finish — is prepared based on the substrate and cutting conditions.

  • Dimensional Inspection and Batch Documentation

    Key dimensions are measured using CMM and calibrated gauges. Edge condition, flatness, and hardness results are recorded per batch to support incoming inspection and repeat-order consistency.

Frequently Asked Questions

Have questions about custom machine knives, materials, or ordering requirements? Here are the most common questions from OEM buyers, maintenance teams, and industrial processors.

Ask an Engineer
  • What information do you need for custom machine knives?

    Please share your application, material type, thickness, cutting method, target cut quality, and blade dimensions if available. Drawings, photos, or physical samples can help us evaluate your requirements faster.

  • How do you choose the right blade material for different cutting applications?

    Blade material selection depends on the material being cut, thickness, cutting speed, and wear conditions. We typically recommend tool steel for balanced performance and carbide when higher wear resistance and edge stability are required.

  • Do you support prototype or trial orders before mass production?

    Yes. We support small-batch trial orders so you can verify blade fit, cutting performance, and service life before moving to repeat production.

  • What tolerances can you control for custom machine knives?

    We control key dimensions such as thickness, outer diameter, inner bore, and flatness based on application requirements. Tolerance levels are defined according to your machine setup and cutting precision needs.

  • How do you ensure consistency across repeat orders?

    We standardize machining, heat treatment, and grinding processes, and maintain inspection records to ensure dimensional stability and consistent edge quality across batches.

  • Can you recommend blade hardness or coatings based on wear problems?

    Yes. If you are experiencing issues such as rapid wear, chipping, or poor cut quality, we can recommend adjustments in material, hardness, or coatings based on your application and wear conditions.
