Manufacture of Toothed Wheels  Manufacturers, Traders, Suppliers

• Choice of material (TPU, PA, POM, ABS, PE, etc.): It all depends on the chemical and physical conditions to which the parts are exposed. With our own toolmaking, mouldmaking and design departments, we can offer you a full service.
• Numerous potential applications: Our ester and ether materials are very hardwearing and flexible and are used in applications with the toughest mechanical demands, e.g. sowing and sifting systems.
• Two components: A glass fibre-reinforced material plus a soft inner coating result in products that can be used as loadbearing parts, for example. Such parts would be inconceivable without precise planning plus development and test phases.
• Test samples: Before ordering an injection mould, we often produce samples for approval using laser sintering or 3D printing to avoid the need to invest in a mould at this stage. Our machines can produce injection-moulded parts weighing between 5 and 6000 g.

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.
Sustainability is important for us at all levels – both in economic and social terms as well as in ecologic terms. In addition to a long-term policy of balanced growth, our focus is on enduring customer relationships. By running a corporate health management programme, we focus on securing the health of our employees. 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.

Technical Data for the Manufacture of Toothed Wheels1. Material Selection & Preparation

• Materials:

• Alloy Steels (e.g., 42CrMo4, 34CrNiMo6): Widely used for their excellent strength, toughness, and fatigue resistance.
• Carbon Steels (e.g., C45, AISI 1045): Chosen for cost-effectiveness and good machinability in less extreme applications.
• Stainless Steels (e.g., 304, 316): Employed when corrosion resistance is essential.

Material Preparation:

• Raw materials are typically supplied in bar or forging form.
• Prior to machining, materials may undergo pre-heat treatments to refine grain structure and reduce internal stresses.

2. Machining Processes

• Gear Hobbing & Shaping:

• CNC Gear Hobbing Machines: Utilized for generating the initial tooth profile.
• Milling and Shaping: For complex profiles or non-standard geometries, dedicated CNC milling centers are used.

Precision Grinding:

• Internal Grinding: Employed to achieve high accuracy and surface finish, particularly for fine-toothed wheels.
• Profile Grinding: Ensures the involute curve is accurately produced, crucial for smooth meshing.

Tooling & Fixturing:

• Specialized cutting tools and fixtures are designed to maintain dimensional accuracy and minimize vibration during the process.
