About us
Tecpa s.r.o. is a Czech company with more than 20 years of tradition, which provides services in the field of precision engineering production with a focus on piece and small-batch production. We provide our customers with comprehensive services from design simulation to production itself.
We specialize in the production and machining of precision parts from materials such as stainless steel, titanium, aluminum, copper, tungsten, graphite, MACOR ceramics and all plastics on the market (PMMA, PEEK, POM). We usually use these parts for welding and assembly.
Construction
Cooperation with customers
Our standard is consultation with the customer, which leads to defining requirements and outlining possible design and production solutions. Based on experience, we are able to detect possible technological risks very early and flexibly propose changes or optimizations right from the beginning. Partial consultations are suitable, whether it is a complete activity in the form of conceptual, design, technological and production, or a standard optimization of the part and direct production based on the supplied documentation.
Research and Development
In addition to standard production, the company focuses on participating in or leading research and development projects, which can be divided into 3 basic types.
- External projects – comprehensive cooperation with the customer from the idea to the final product. This often involves the development of a new or modified unit or part of diagnostic equipment, scientific instruments or mechanisms.
- Internal projects – projects focused on the development of production know-how, technological innovation and strengthening the company's competitiveness on the market.
- EU subsidy projects – leading or participating in R&D projects in collaboration with other research organizations, universities or commercial enterprises.
This leads to the creation of research consortia composed of experts across different fields, usually with the aim of creating functional units of instrumentation or diagnostic equipment for the purpose of scientific, medical or industrial practice.
Products
Vacuum components
We currently manufacture several types of vacuum components.
Electrodes for resistance welding
We manufacture electrodes for resistance welding.
Lightguides
We design and manufacture light pipes.
Other components
We also manufacture a wide range of custom-made components.
Technology
Production preparation
Before production, our products undergo preparatory process with an emphasis on design and technological feasibility. For this process we use:
• SOLIDWORKS
• hyperMILL
• 3D print
Non-standard machining methods
Standard machining methods have some limitations. For this reason, we use a number of innovative machining methods, for example:
• interpolation turning
• scratching
Welding and orbital welding – high quality and precision
The main advantages of precision laser welding technology are that the welded materials are exposed to minimum pressure and welding is achieved with maximum accuracy, which ensures repeatable and high quality results. We use state-of-the-art equipment (AMADA MIYACHI NOVA6) for laser welding of metals, suitable for both series production and scientific research projects.
Our expertise in the field of welding also includes orbital TIG welding, ie welding of circular assemblies, located in difficult to access areas deep inside the components. Even in such cases, we guarantee high quality and repeatability of the weld. Thanks AVC technology (Automatic voltage control eliminating the effect of electrode wear) we can ensure accurate welding results even on parts with uneven surface geometry.
Surface finishes
The final look and finis his absolutely essential for high-tech products. One example is PMMA light guides, which we polish to perfection to ensure optimal light reflection. For stainless steel weldments, used in vacuum technology, we use a number of other sophisticated methods for surface treatment, which is essential not only for their function.
Washing
The standard process, common to all manufactured parts, is to clean and wash them. We remove dirt, cutting fluids and oils in dips or baths of various chemical compositions in professional ultrasonic dishwashers. Subsequent drying of parts takes place in adapted heat dryers or by a flow of compressed air.
Assembly (construction)
We also deal with the assembly of parts into larger assembly units, especially by joining into vacuum or vacuum-tight assemblies. Fully and efficiently equipped high-clean rooms are used for this purpose.
In addition to conventional assembly in the form of detachable connections, we also specialize in non-detachable connections using LBW or TIG welding or vacuum soldering.
Packing
Most of our production is very sensitive. We therefore place emphasis on comprehensive protection of parts, both with conventional packaging material and our own custom-made packaging and cases. You can be sure that our products will be packed with care and delivered in 100% condition.
Strict quality control system
Our company adheres to a strict quality control system, which allows us to manufacture sophisticated components such as instrument and vacuum assemblies for electron beam microscopes, tested with a custom-made helium leak detector.
Our customers expect tight tolerances, repeatability down to a hundredth of millimeter, precise welds, vacuum tightness up to 10th order and unique appearance. We strive to continuously improve our quality control system.
News
Implementation of the project "Innovative activities in the field of electron microscopy instrumentation"
The goal of the project is to increase the innovative performance and competitiveness of Tecpa s.r.o. by enabling the production of a new type of backscattered electron detector with a linear or curved light guide usable in scanning and environmental scanning microscopes.
