PVTech includes a wide variety of materials to do extensive testing of the products. Some of our test machinery is described below

Profile Projector

The profile projector is used for measuring two-dimensional contours of precision specimens. The part to be measured is magnified by an optical system and projected on a screen. 

Specific Gravity Test

Specific gravity is commonly used in industry as a simple means of obtaining information about the concentration  of solutions in various types of components like Rigid PVC,Soft PVC,TPE, HDPE, LDPE material

Tensile Testing

Tensile Testing of materials is a destructive test process that provides information about the tensile strength, Elongation of the material. Laboratory Testing performs the tensile test  in accordance with industry standards and specifications, including ASTM tensile test methods.


To check colour matching using this calorimeter is easy to identify the variation. First check the master sample and set the target value to stored after will check the specimen sample.The colours are match probably it shows "Pass", colours are not match it shows "Fail".

Hardness Testing 

Hardness is defined as the resistance to indentation, and it is determined by measuring the permanent depth of the indentation. PVTech performs various hardness tests based on the size of the sample being tested. Shore A is used for soft products (Waterstop) and Shore D is used for hard products


Video measuring machine

This Video measuring machine can directly measure the some kind of elements such as line, circle, arc,elipse, rectangle,slot,O-ring,distance, angle, height, focus paln, curve,closed curve,radius.



Impact Testing 

The purpose of impact testing is to measure an object's ability to resist high-rate loading. It is usually thought of in terms of two objects striking each other at high relative speeds.


This test is outlined by ASTMD4726-15, D3678-14, D4226-16 and D421613 guidelines. The degree of resistance to breaking on impact, and its measurement, is of practical importance in the selection and comparison of plastics.



Shrinkage Test



Shrinkage in PVC tends to be between one and two percent but can vary based on a number of factors including material durometer (hardness), gate size, holding pressure, holding time, melt temperature, mold wall thickness, mold temperature, and the percentage and type of additives. Shrinkage test hence verifies if the shrinking of the PVC is of acceptable standard and meets customer requirements.

Impact Drop Test

Weights are dropped on the samples to observe if the mechanical property , molecular flexibility and strength of the material meets consumer requirements.
