Instrument Design and Fabrication

Smithers Pira's experience in instrument design and manufacture is complimented by our extensive knowledge of physical testing.

Our innovative and bespoke designs offer effective solutions when commercial equipment is not available or does not fulfil customer requirements.

Our instrument design and fabrication team is comprised of skilled software and design engineers with expertise which covers complex computer controlled multi-axis electro-mechanical systems, through to simple test fixtures, sample moulds and templates. Instruments produced are CE marked and conform to the essential requirements of EC directives, whilst instrument software is USB interfaced and windows compatible.

Typical applications include:

  • Precision control
  • Force and load measurement
  • Temperature/humidity
  • Friction
  • Density
  • Leakage

An onsite workshop permits us to promptly manufacture a complete solution, whilst allowing our engineers to work with your team from prototype through to production. We deliver a flexible, cost effective and efficient service which is appropriate to the customer's requirements.

Examples of Custom Instrument Design and Fabrication

Impact Testing

Smithers Pira has recently developed an instrumented impact tester which is suitable for testing materials, packaging and products.

Using an impact load similar to the weight of the product, and an impact speed equivalent to a drop height of up to 1m, Smithers Pira can employ the impact tester to assess and compare material and product performance mimicking real world situations.

High tech instrumentation and a custom made software package allow sampling up to 45 kHz recording an impact force trace with automatic determination of the peak impact force, total energy absorbed and material deflection at point of failure.

In house workshop facilities and an experienced design team give us the flexibility to rapidly manufacture fixtures and mounting systems to accommodate small, medium and large samples and accurately target identified problem areas.

Our impact tester is portable and can be operated within a climate chamber at temperatures between -40°C and +40°C.

 

Leak Detection

The integrity of non-porous packaged can be tested using a pressure decay method; the pack is pressurised to a small over pressure, typically 15-50mbar, and the rate of pressure decay is monitored using a digital pressure sensor allowing the size of the hole present in the pack to be determined.

At Smithers Pira our instrument design and fabrication team have experience in manufacturing bespoke leakage testers which employ the pressure decay method. Custom design allows the machine to be tailored to the clients’ specific product or package requirements.
