What is Tolcap?

Tolcap is an online tolerance analysis tool that predicts the capability of your tolerances before you start production. It produces reliable tolerance charts for every product design need. Tolcap uses data collected over 20 years to give you complete confidence in its tolerance capability predictions. Whether you design for manufacture or design for assembly, you will not find a tolerance analysis tool like this anywhere else.

Tolcap was designed and built in the UK by two Yorkshire businesses: CapraTechnology (who provide the engineering expertise) and Codebase Consulting (who designed and maintain the online tool).

Our vision is for worldwide instant availability of reliable tolerance capability data for every product design requirement.

Tolcap is good news for engineers, designers, manufacturers and accountants! After just a few hours of use, you'll wonder how you managed without it!

  • Increased Profitability

    Tolcap reduces the cost of quality by identifying problems at the design stage and ensuring the manufacturability of the design. Capable tolerances = reduced costs = increased profitability.

  • Right First Time Manufacturing

    By making sure you are working with capable tolerances at the design stage, "Right First Time" manufacturing is an achievable goal.

  • Supply Chain Satisfaction

    Use Tolcap to predict tolerance capability and share the predictions with your supplier. Tolcap brings a shared problem-solving approach to replace combative supplier discussions.

  • Six Sigma Defect Reduction

    Tolcap can help your company achieve six sigma quality by making sure your tolerances are capable and will remain capable over time.

  • Better Design & Manufacturing Decisions

    Tolcap provides capability maps for over 80 manufacturing processes, helping you pinpoint the most efficient production method by examining alternatives for cost and capability.

  • Equal Opportunity

    If you have a "stack" of dimensions where parts fit together, it is important to know if the stack is capable. Tolcap enables equal process capability of the parts, which also ensures you have minimum defects.
