A Complete Guide for Choosing Felt Cutting Underlay for Jwei Cutting Machines
When your Jwei cutting machine starts showing problems such as incomplete cutting, material slipping, excessive blade wear, or uneven cutting quality, the cutting underlay is often the part that needs attention.
A high-quality cutting underlay plays an important role in supporting the material during the cutting process. Choosing the correct felt conveyor belt not only improves cutting accuracy but also helps extend blade life and maintain stable machine performance.
SCplus Belt provides customized felt cutting underlays compatible with Jwei digital cutting machines, available in different sizes, thicknesses, colors, and joint solutions to meet different cutting applications.
1. Why Does the Cutting Underlay Matter for Jwei Cutting Machines?
The cutting underlay is the working surface directly supporting your materials during cutting.
During continuous cutting operations, the underlay needs to handle:
Frequent blade penetration
High-speed cutting movements
Continuous friction from materials
Vacuum suction from the cutting table
Long production hours
A low-quality or worn cutting underlay may cause:
Reduced Cutting Accuracy
A damaged surface cannot provide stable support, causing the blade depth to become inconsistent.
Faster Blade Wear
When the cutting surface becomes uneven, the blade experiences additional resistance and wears faster.
Material Movement During Cutting
Insufficient friction between the material and underlay may affect cutting precision, especially for lightweight materials.
Increased Machine Downtime
Replacing the underlay too frequently increases maintenance time and production costs.
A suitable felt cutting underlay helps maintain stable cutting performance and improves overall production efficiency.
2. How to Choose the Correct Cutting Underlay Size for Jwei Machines?
The first step is selecting the correct dimensions.
Different Jwei cutting machines may require different belt sizes depending on:
Cutting table width
Conveyor length
Machine model
Installation requirements
SCplus Belt supports customized sizes, including:
Width: Customized according to machine size
Length: Customized according to conveyor structure
Thickness: 2.0mm / 3.0mm / 4.0mm / 5.0mm / 5.5mm or customized
Color: Gray / Black / Green / Blue
Joint: Single finger joint / Double finger joint / Skived overlap joint / Custom
Whether you need a standard replacement belt or a completely customized solution, SCplus Belt can manufacture the cutting underlay according to your machine specifications.
3. Choosing the Right Thickness: 2mm, 3mm, 4mm or 5mm?
Thickness directly affects the service life and cutting performance of the underlay.
2.0mm – 3.0mm Cutting Underlay
Suitable for:
Light cutting applications
Lower cutting pressure
Frequent replacement requirements
Advantages:
Flexible installation
Lower cost
Easy replacement
4.0mm Cutting Underlay
A commonly selected thickness for many industrial cutting applications.
Suitable for:
Textile cutting
Leather cutting
Composite material cutting
General digital cutting operations

Good balance between durability and cutting performance
Stable blade support
5.0mm – 5.5mm Cutting Underlay
Recommended for:
Heavy-duty cutting applications
High production environments
Long operating hours
Advantages:
Longer service life
Better resistance against repeated blade impact
If you are unsure which thickness is suitable for your Jwei machine, SCplus Belt can recommend the best option based on your material and cutting conditions.
4. Which Cutting Underlay Joint Type Should You Choose?
The joint design directly affects installation smoothness and belt running stability.
SCplus Belt offers multiple joint solutions:
Single Finger Joint
Suitable for general applications.
Features:
Easy installation
Good running performance
Cost-effective solution
