[ The Industry Challenge ]
The Real Cost of Wear.
Processing mixed polymers introduces severe abrasive wear. Standard blades degrade rapidly, and traditional screen filtration forces frequent, costly line shutdowns.
[ Sureay Engineered Solution ]
Engineered to Run Longer.
Filterless Systems eliminate manual mesh replacements, while our extreme-hardness Tungsten Carbide blades maximize continuous pelletizing (+30% Uptime).

OEM Process From Drawing To Delivery
Get In TouchA custom blade order moves through four clear steps — so you know what to send, what we confirm, and what gets checked before shipment.
Send Drawing Or Sample
Send your drawing, used sample, machine model, or key dimensions. We review the application, blade geometry, material being cut, and any known fit or wear issues from your current supplier.
Engineering Review
Our engineers confirm steel grade, heat treatment direction, tolerance target, edge profile, and all OEM-fit details. Any open questions are resolved before quotation or production approval is issued.
Machining And Hardening
The blade moves into CNC machining, vacuum heat treatment, and precision grinding in a controlled sequence. Each stage is tracked against the approved specification to prevent distortion and geometry drift.
Inspection And Shipment
Final dimensions, hardness, and edge condition are verified against specification before dispatch. The order is packed and shipped with the required inspection records, and material certification documents.
