Box Production Lines
Replacement wear surfaces for corrugated packaging production.
Printed Corrugated Board
Supports die cutting of flexo-printed boxes and corrugated sheets.
Replacement Covers
Made to replace worn or aging anvil covers from machine data or samples.
Continuous Production
Suitable for demanding, high-frequency rotary die-cutting conditions.
Quick-Change Systems
Finger-lock structures support practical installation and routine replacement.
HOW TO MEASURE BEFORE REQUESTING A QUOTE
Eight Details That Help Confirm the Correct Anvil Cover
Clear measurements and photos reduce uncertainty and help us review the correct dimensions, hardness and locking structure.
Machine Brand and Model
Share the machine nameplate photo whenever available.
Die-Cutting Cylinder Diameter
Measure the cylinder diameter at the anvil-cover installation position.
Cover Width
Measure the full width of the current polyurethane cover.
Cover Thickness
Measure the PU layer or the complete cover thickness and identify which value is supplied.
Slot Width and Depth
For steel-backed or locking systems, measure the slot width and depth.
Locking Structure Photos
Photograph the joint, end face and back structure clearly.
Hardness Requirement
Provide the original hardness if known; otherwise share the machine and operating conditions.
Drawing or Physical Sample
If dimensions are uncertain, send a drawing or arrange a sample for confirmation.

FREQUENTLY ASKED QUESTIONS
Polyurethane Anvil Cover FAQ
Can you make an anvil cover for my machine model?
Yes. Send the machine model, current cover photos, drawing or physical sample. We will review the actual structure and confirm the dimensions.
What is the difference between steel-backed and finger-lock covers?
Steel-backed covers are suited to demanding continuous die cutting and provide a stable structure. Finger-lock covers are easier to install and replace. The correct choice depends on the machine design.
Can the hardness be customized?
Yes. Hardness can be selected according to machine pressure, board material and die-cutting requirements.
What information is required for a quotation?
Provide the machine model, cylinder diameter, cover width and thickness, slot width and depth, hardness, quantity and clear photos of the current cover.
Is the service life fixed?
No. Service life depends on cutting pressure, die condition, board material, machine adjustment, rotation practices and maintenance. The figures on this page are reference values only.
Can you produce from a sample if I do not have a drawing?
Yes. You can send a physical sample for measurement, structure review and mold development.
Is repeat ordering straightforward?
Yes. After the dimensions and structure are confirmed for the first order, we can retain the production reference to arrange repeat orders more efficiently.
