Hydraulic GSM Cutter
Hydraulic GSM Cutter
A Hydraulic GSM Cutter is a precision instrument used to cut circular fabric samples for GSM (Grams per Square Meter) testing. It uses hydraulic pressure to ensure clean, uniform cuts through multiple fabric layers, making it ideal for high-throughput or thicker materials.
Purpose of Hydraulic GSM Cutter:
– To prepare accurate circular samples (usually 100 cm² area) for determining fabric weight in GSM.
– Used widely in textile testing labs for quality control and consistency.
Working Principle of Hydraulic GSM Cutter:
– Fabric is placed on a cutting pad.
– The cutter, equipped with a sharp circular blade, is hydraulically pressed down on the fabric.
– The cut sample is then weighed to calculate GSM using a formula or GSM scale.
Applications of Hydraulic GSM Cutter:
– Suitable for woven, knitted, and nonwoven fabrics.
– Used in textile mills, labs, and R&D centers.
Benefits of Hydraulic GSM Cutter:
- High Cutting Precision – Ensures consistent and accurate fabric sample size for reliable GSM results.
- Effortless Operation- Hydraulic action reduces manual effort and operator fatigue.
- Ideal for Thick or Multi-Layer Fabrics – Cuts through dense or multiple fabric layers cleanly.
- Time-Saving – Speeds up the sample preparation process, especially for high-volume testing.
- Improves Test Accuracy – Uniform samples help eliminate errors in GSM calculation.
- Durable and Long-Lasting – Robust construction ensures stability and extended service life.
- Safety Enhancement – Reduces risk of injury compared to manual rotary cutters.
- Consistent Pressure Application – Hydraulic mechanism maintains steady force for each cut.
Features of Hydraulic GSM Cutter:
- Hydraulic Press Mechanism – Applies consistent and strong pressure for clean, even cuts.
- Standard Cutting Die (100 cm²) – Produces fabric samples suitable for GSM testing with standard area.
- Heavy-Duty Construction – Built with robust metal frame for long-term lab or industrial use.
- Sharp Stainless Steel Blades – Durable and replaceable blades ensure smooth, precise cuts.
- Cutting Pad Included – Comes with a rubber or nylon base to protect blades and ensure clean edges.
- Simple Lever or Button Operation – Easy to use with minimal training required.
- Non-slip Base – Provides stability during operation for safe, accurate cutting.
- Supports Various Fabric Types
– Suitable for woven, knitted, nonwoven, technical textiles, and coated fabrics.
How to Use Hydraulic GSM Cutter:
- Place the Cutting Pad – Lay the rubber or nylon cutting pad on a flat surface.
- Position the Fabric – Place the fabric sample flat and smooth on the cutting pad.
- Align the Cutter – Position the GSM cutter die over the desired area of the fabric.
- Activate Hydraulic Press – Pull the lever or press the button to apply hydraulic pressure and cut the sample.
- Remove the Sample – Lift the cutter and carefully take out the circular fabric piece (usually 100 cm²).
- Weigh the Sample – Place the cut sample on a precision balance or GSM scale to determine weight.
- Calculate GSM – Multiply the sample weight (in grams) by 100 to get GSM.
GSM Formula (Grams per Square Meter):
GSM is used to measure the weight of fabric and indicates its thickness and quality.
Formula:
GSM = (Sample Weight in grams × 10000) / Sample Area in cm²
For standard cutters that cut 100 cm² samples:
GSM = Sample Weight (in grams) × 100
Example:
– If a 100 cm² fabric sample weighs 1.5 grams:
GSM = 1.5 × 100 = 150 GSM
