Rigid plastic testing equipments manufacturers in India provide the base kit for resin compounders, moulders and product makers, who must show that a part meets its property sheet. Civil Mechanical India is one of the suppliers in India of ASTM and ISO style plastic testers that sit alongside its sector-specific pipe, tank and bottle ranges.
Plastics are described by a short list of properties. Strength and stiffness come from the universal testing machine and flexural fixture. Toughness comes from Izod and Charpy pendulum, falling weight impact and the notch cutting machine that prepares notched specimens. Heat performance comes from HDT and Vicat testing, flow from melt flow index, and long-term behaviour from the ESCR bath. Hardness and density finish a typical property report.
The group suits general moulding and sheet plants, and it supports the narrower product ranges for pipes, tanks, caps and bottles.

Rigid plastic equipment tests material properties on standard specimens, such as tensile bars or impact blocks, that apply to any moulded or extruded plastic. Pipe instruments test the product, including hydrostatic pressure, ring stiffness, reversion and impact on finished pipe lengths. A pipe plant will usually buy both: material property machines to approve resin and pipe machines to approve the product.

The complete Rigid Plastic Testing Equipments range (10 products), in alphabetical order:
List the polymers and product forms, then match standards: ISO 527 or ASTM D638 for tensile, ISO 178 for flexure, ISO 180 or 179 for impact, ISO 75 for HDT and ISO 1133 for melt flow. Check load ranges, temperature capability, specimen preparation needs and software. Also plan for notching and specimen cutters.
Izod clamps the specimen as a cantilever, Charpy supports it as a beam, so results are not interchangeable. Choose the one your resin supplier or customer cites. A combined pendulum with both fixtures and several hammers gives flexibility, but notch quality must be controlled with a dedicated notching machine.
For batch checks on incoming resin, the melt flow index tester is enough and is economical. A capillary rheometer is needed only for process studies across shear rates. Check the barrel and die tolerances, temperature stability, cutting method for extrudates and the weights offered for your materials.
Plastic moulders and extruders, resin compounders, masterbatch makers, auto and appliance parts suppliers, plastic pipe and tank manufacturers, and independent testing laboratories buy this range. A first order often includes a universal machine, impact tester and melt flow tester, then HDT or ESCR equipment is added when a customer specification or product failure analysis calls for them.
Heat deflection temperature is the temperature at which a loaded bar deflects by a set amount while heated in a bath. It indicates the upper limit for load-bearing use, so designers and moulders use it to compare materials and grades.
A 50 kN frame can test plastics, rubber and some metals with suitable grips and load cells. For plastics, a lower capacity load cell improves accuracy at small forces, so mention the specimens you intend to test.
Yes. Civil Mechanical India supplies moulders, compounders and labs across India and also exports. Packing, installation and operator training details are confirmed in the written quotation.
Environmental stress crack resistance exposes stressed polyethylene specimens to a wetting agent at controlled temperature and records time to cracking. It is widely used for bottles, closures and tanks that hold detergents or chemicals.
PC software with stress-strain curves is available for the universal machine, and calibration checks are done before dispatch. Request certificates in your enquiry if your quality system needs them.
