Tear Tester
This procedure is utilized for measuring the tear strength of thermoplastic films or non-rigid sheets. Through this test method, we determine the average force required to propagate tearing through a specified length of plastic film or non-rigid sheeting.
This test method is valuable for ranking the relative tearing resistance of various plastic films and sheets of comparable thickness.
Unique Selling Proposition (USP)
It consists of stationary and movable clamps, a stopper for holding the pendulum in a raised position and releasing it instantaneously, and an indicating device for taking the reading of pendulum swings when released. Additionally, a template die or shear-type cutter is included for cutting specimens.
The equipment is recognized by various names such as Tear Strength Tester, Tensile & Tear Strength Test Equipments, Tear Resistance Tester, Digital Tear Strength Tester, Tear Strength Testing Machine, Plastic Film & Sheet Tear Strength Test Equipment, Plastic Lab Sample Tear Strength Tester, etc.
Dart Impact Tester (Pneumatic Holding)
The impact properties of polymeric materials directly influence the overall toughness of the material.
Toughness is defined as the polymer’s ability to absorb applied energy. Plastic films are commonly utilized for packaging purposes and are subjected to wear and tear. Therefore, the strength of impact resistance is crucial for assessing the quality and determining the impact load the film can withstand.
This method involves evaluating the energy that causes plastic film to fail under specific conditions of the impact of a freely falling dart.
Machine is Designed According to ASTM
Pneumatically Operated Clamps have been used to hold Film.
Electromagnetic Centering device provided to Ensure reproducible drop.
Dart drop mechanism is providing to dart drop at different Drop height.
Free Falling Dart Impact Tester (For Film)
This Dart Impact Tester is for different plastic films, sheets, Decorative laminates, corrugated roofing sheets etc. with range of Darts & selectable facility of height of fall with low efforts. Its also offer two different Electromagnetic system for light & heavy Dart respectively which would help in selection of dart with smallest possible dart to heaviest one. Tester is equipted with high tech vaccum pump with gauge and clamping system to clamp the film tightly and digital counter for counting no. of test.
Color Matching Cabinet
Metamerism is a phenomenon in which test samples appear to match under one light source but appear different when viewed under another light source. Color Matching Cabinets are devices designed to confirm the color consistency of various products.
Vishva’s Color Matching Cabinet offers a standardized environment for the evaluation and visual assessment of color. It is strongly recommended for laboratories to assess the quality and color consistency of paint, plating, textiles, paper, and more.
Ditigal Thickness Gauge Meter
A digital thickness gauge meter is an essential tool used in plastic converting machine testing. It accurately measures the thickness of plastic sheets, films, or other materials during production. This allows for precise control and quality assurance of the plastic conversion process, ensuring desired thickness specifications are met.
