Small metal parts - Import export

Parts are made to custom design from drawings, from very small quantities to industrial mass application, pursuant to standards, in a wide range. We supply components in accordance with customer requirements, with a special or knurled surface, and with a range of head forms, such as ring, eyelet, hook, triangle or ligature. Screws, bolts and axles from 1.5 mm to 12 mm can be made with lengths of up to 397 mm; customer lengths available on request (also on request with lock serrations). Knurled axles (knurling either DIN or to customer requirements), threads of M2 to M12 made of plastic or wood or with rolled thread, thick or thin shafts. Ligatures with threads of M2 to M8, or wooden thread with or without weld warts. Rivets and pins with diameters of 1.2 mm to 10 mm, with or without bevelling. Also knurled (knurling either DIN or to customer requirements).

We employ welding robots to join complex metal wire parts made of steel or aluminium to form an assembly. This in turn leads to complex bent wire components for the automotive industry, such as brackets for cushioning frames, and eyelet fastenings.

With over 125 years of market experience, a network of specialised companies has evolved to serve the wide range of your customers’ requirements with the best possible quality. The focus of these long-standing cooperations is on making the most of available know-how while maintaining fair market prices. Besides bent wire and plastic components, a wide range of industries also require so-called hybrid parts. This combination of metal and plastic is found, for instance, in screw joints, connecting rods, seat elements for lumbar support, and medical engineering, among other areas. We work in close cooperation with specialised partners for plastics engineering. Our great efficiency in wire working technology and plastic injection enables us to create hybrid parts that satisfy the most stringent requirements.

Parts are made to custom design from drawings, from very small quantities to industrial mass application, in a wide range. We work with steel, stainless steel, copper and aluminium wire and can also implement your surface requirements.

Processes such as radial riveting or pressing are used to permanently conjoin a metal plate for example with a wire bracket. 
Test apparatus for monitoring compliance with the required tear values secure the process in line with these safety-relevant components. These assembly parts are used, for example, as reinforcements for backrest frames.

Continuous flow pretreatment plants are designed for high throughput and consist of cleaning stages (degreasing), rinsing stages and possibly layer-forming processes such as phosphatisation. Continuous flow pretreatment Continuous flow pretreatment plants are universally usable. Their high throughput performances in particular make them interesting for many applications. Spraying rings apply different media to the components as they pass through. In the successive zones, therefore, the parts can pass through a cleaning programme tailored to the particular application that guarantees optimum and constant quality. Rippert builds continuous flow plants for small sheet metal parts up to large-scale drag cleaning with a high quality of workmanship. Multi-channel pretreatment plants are also possible, as is combined pre-cleaning by means of robots.
