PRODUCT OVERVIEW

Made around the machine, cylinder and replacement method

Anvil covers receive repeated die contact. Diameter, width, thickness, hardness and locking fit work together to determine installation and cutting consistency.

01Blue TDI and gray MDI material routes
02Steel-backed, finger-lock and machine-specific structures
03Review from machine model, drawing or physical sample
04Confirmed dimensions can be archived for repeat supply

Review around real machine data

01

Material route

Review TDI or MDI against output, downtime and operating conditions.

02

Structure match

Build around the cylinder groove, locking ends and current-cover design.

03

Dimension control

Confirm cylinder diameter, working width, thickness and section count.

Two material routes, matched to the workload.

TDI Blue

Internal test reference: approximately 3 million cutting cycles. A route for routine production and planned replacement.

MDI Gray

Internal test reference: approximately 7 million cutting cycles. Review around cycle load and replacement downtime.

Confirm the application

Both routes require confirmed dimensions, hardness and lock geometry. Die condition, pressure, board, rotation and maintenance affect actual life.

These are internal test references, not fixed service-life guarantees.

Joint and fit on our demonstration drum

Installation on our in-house demonstration drum
Installation on our in-house demonstration drum

The blue cover is mounted on a demonstration drum made in our workshop to show the interlocking joint and fit. For a replacement, send joint photos together with drum and cover dimensions.

This is an in-house installation display, not a customer production installation or a life test.

Finger-lock installation and removal reference

  1. Clean the grooves and mounting surfaces.
  2. Rotate and align both ends evenly.
  3. Use a rubber hammer to seat the locking area.

Follow the machine structure and site maintenance procedure for the final method.

Frequently asked questions

Can you review a replacement from an old cover?

Send overall, end and joint photographs with drum diameter, width and thickness. Complex structures may need a drawing or physical sample.

How are steel-backed and finger-lock options selected?

Match the existing groove, locking approach and replacement routine. Colour or machine brand alone does not establish interchangeability.

Are 3 or 7 million cycles guaranteed?

No. These are internal test references. Machine condition, die, pressure, board and maintenance affect actual results.
