As one of the leading manufacturers and further processors, ISO-TECH has been producing high-quality thermoplastic products for domestic and foreign customers for more than 30 years. A broad range of production possibilities, a sustainable corporate policy and a distinct customer orientation characterize our company.
After founding the company in 1990 with initially four employees, we quickly established ourselves as a specialist in the technical plastics segment. With the help of a continuous organic growth, we have steadily expanded both the production of semi-finished goods and the range of finished parts. The first milestones were already achieved in 1995, when we were initially certified according to ISO 9001 and the staff had grown to more than 20 employees. With the opening of a second plant in 2010, we were able to expand our range of products by additional high-performance plastics. With the 25th anniversary in 2015, our owner-managed company was delivering goods into almost all branches of industry. Today, ISO-TECH employs roundabout 200 people and invests continuously in the expansion of the production range and vertical integration.
Our range of products varies from our own production of semi-finished goods to variously processed finished parts made of standard and engineering plastics or high-performance plastics. In the semi-finished goods segment, we produce plastic sheets in various standard dimensions and thicknesses However, a large part of our semi-finished goods is being processed inside our plants into individual machined parts. In addition to large as well as prototype-series, we offer our clients individually customized products. Both high and ultra-high-molecular-weight polyethylenes (e.g. PE500, PE1000) as well as polyamides (PA), polyoxymethylenes (POM) and other materials like PVDF or PEEK are being machined in our factories. A distinctive quality management, constant education and training of our employees as well as a precise selection of raw materials ensure the reliability of our products.

Furthermore, we are making an important environmental contribution by recycling 100% of our polyethylene material waste and by constantly investing in energy efficiency measures and renewable energies.

Precision metal or non-metal parts manufactured by CNC lathe, using rotary cutting technology to form materials with high precision.

Lathe-machined components (e.g., shafts, pins) with micron-level tolerances, often from metals or engineering plastics for mechanical assemblies.

CNC lathe can process linear cylinder, oblique cylinder, circular arc and a variety of thread, groove, worm and other complex products. Our products have been widely used in photography equipment, medical industry, aerospace, auto parts, electrical instruments and other industries.

CNC turning is a manufacturing technology that involves precision machining by means of a computer programme controlled lathe. It uses the relative motion between a rotating workpiece and a fixed tool to remove material to form the desired geometry. Compared to traditional manual turning, CNC turning offers a higher degree of automation, accuracy and repeatability, and is suitable for the mass production of complex parts

The main process of CNC milling usually includes the following steps:
CAD design
Use computer-aided design software to draw a three-dimensional model of the part to determine the various machining features and dimensional requirements.
CAM Programming
The CAD model is imported into a computer-aided manufacturing (CAM) system, and the model is converted into G-code through tool path planning. This stage requires the setting of appropriate parameters such as cutting speed, feed rate and depth of cut.
Machine setup
The operator fixes the workpiece on the table, installs a suitable tool and carries out zero calibration to ensure that the machine coordinates match the workpiece.
Trial Cutting and Formal Machining
Before formal machining, a simulation or test cut is usually carried out to verify that the programme is correct, and then the actual milling process begins.

Our various processing technology main production products include: equipment spare parts, product shells, mechanical parts, chassis cabinet shells and so on. These products are widely used in intelligent security, 3C, automotive, medical, smart grid monitoring and other fields.
