What WIMA Control does

WIMA Control GmbH Qualitätsprüfung is a family-run German quality-testing service provider founded in September 1991 by Reinhold Willems and Walter Marienfeld (the company name derives from their surnames). Headquartered in a 3,300 m² purpose-built facility in Velbert, North Rhine-Westphalia, the company employs approximately 40 staff across two shifts and operates 29–30 state-of-the-art sorting machines. It is currently led by Managing Directors Walter Marienfeld and Patrick Ruhrmann (since April 2022), representing the third generation of family ownership.

The company's core service is contract sorting: 100% inspection, testing, sorting, and packaging of screws, nuts, washers, and other fasteners. Three complementary inspection modules are deployed — camera-based optical inspection with up to 9 cameras per system covering geometry, thread, drive presence, surface defects, and topography; eddy current testing for finest shear and hairline cracks in conductive fasteners; and tactile drive checking with 10 rotating test bits for hexalobular, hexagon socket, and multi-tooth drives. Throughput is 120 million fasteners per month, with peak capacity of 5 million per day and a guaranteed 10 ppm grade purity. Screws from 1.4 mm to 16 mm thread diameter (up to 140 mm length) and fasteners up to 42 mm diameter and 38 mm height are within scope, with subsequent packaging in customer-specified containers and full inspection-report documentation.

Revenue is generated through B2B, sales-led engagement: customers contact the company directly for project quotations, with detailed quotes typically returned within 24 hours. Pricing is quote-based and transaction-driven, varying by batch size, inspection complexity, number of test characteristics, and throughput time; both small-batch and multi-year annual contracts are offered. The customer base consists of industrial fastener suppliers to the automotive, mechanical engineering, aerospace, electronics, and furniture industries. The company is certified to DIN EN ISO 9001:2015 (quality) and DIN EN ISO 14001:2015 (environmental management), is an associate member of Deutscher Schraubenverband e.V. since 1996, and operates an on-site 242 kWp photovoltaic system supporting CO2-neutral production goals.

Core offering

WIMA Control provides 100% inspection, contract sorting, and packaging of fasteners (screws, nuts, washers, and other connection elements) for industrial suppliers. Services combine camera-based optical inspection (up to 9 cameras per system), eddy current crack detection, and tactile drive check testing to deliver zero-defect selection with guaranteed 10 ppm type purity. The company processes up to 120 million fasteners per month across 30 sorting machines at its Velbert, Germany facility, with throughput times under 24 hours.

Product overview

WIMA Control GmbH is a family-run company providing 100% inspection and contract sorting services for fasteners. The core offering is Contract Sorting, which is supported by three specialized inspection modules: Camera Inspection (optical testing with up to 9 cameras), Tactile Screw Drive Check (mechanical bit testing), and Eddy Current Testing (electrical crack detection). After inspection, sorted goods are packaged through the Packing service module. The company guarantees 10 ppm type purity for each inspection feature and processes up to 120 million fasteners monthly using 29 state-of-the-art sorting machines.

Functional benefit

Products and services

• Contract Sorting Core service offering providing 100% inspection and sorting of fasteners including screws, nuts, washers, and other connection elements for industrial suppliers. Supports production volumes up to 5 million fasteners per day with guaranteed 10 ppm type purity, and throughput times under 24 hours depending on batch size.
• Camera Inspection Optical inspection service using up to 9 cameras per inspection and measuring system to perform 100% inspection of fasteners. Tests include length, width, height, diameter, thread testing, head cracks, drive presence, surface defects, and topography analysis for screws, nuts, washers and other fasteners.
• Screw Drive Check Tactile mechanical testing service using a rotating device equipped with 10 test bits that press into screw drives to verify drive functionality. Detects drive defects, stripped drives, stamp breaks, and burrs, supporting hexalobular, hexagon socket, internal multi-tooth and other drive types.
• Eddy Current Testing Non-destructive electrical testing service for detecting finest shear and hairline cracks in electrically conductive screws. Uses alternating magnetic field to induce eddy currents in screw heads, with material separations causing amplitude deflection that signals defects.
• Packing Packaging service for sorted fasteners in customer-specified packaging including large containers, cardboard boxes, small load carriers (KLT), polybags, sacks, or company containers. Includes clear labeling (green sticker for OK goods, red label for rejected parts) and inspection reports with quality documentation.

Scale indicators7 records

Recent moves7 records

Expansion highlights5 records

Broad incumbents

• Vitronic GmbH: Established German machine-vision specialist serving industrial inspection and quality control across multiple verticals; WIMA competes with its broader package and could partner with it for component integration.
• ISRA VISION (Atlas Copco): Atlas Copco-owned machine vision and surface inspection platform widely used in industrial quality control, including fastener and metal component inspection, overlapping with WIMA's camera-inspection module.
• Mettler-Toledo: Global precision instruments provider spanning industrial weighing, dimensional measurement, and quality inspection; a broad incumbent whose product portfolio partially overlaps with WIMA's testing and inspection stack.
• Carl Zeiss Industrial Metrology: Global industrial metrology leader offering precision measurement and optical inspection solutions; represents the scale end of WIMA's competitive set and a benchmark for industrial-quality measurement capabilities.

Emerging players

• Asentics GmbH: Siegen-based supplier of industrial inspection, sorting, and joining systems for small parts and fasteners, with overlapping machine-vision and eddy-current capabilities targeted at the same aerospace/automotive supplier base.
• EVK / EVK DI Kerschhaggl: Austrian specialist in optical quality inspection and sorting systems for industrial components, including fasteners; adjacent geographic peer in the DACH region with comparable technology and use cases.

Direct peers

• Steuer Engineering GmbH: German engineering firm that designs and builds complete sorting and inspection lines for fasteners and small parts, directly competing with WIMA in 100% quality inspection for the screw and nut industry.
• Stracke GmbH & Co. KG: Specialist in 100% inspection and sorting systems for turned parts and fasteners, offering camera, eddy current, and tactile inspection technologies comparable to WIMA's stack.

Regional players

• Wirth GmbH: Regional German competitor in fastener and small-component inspection/sorting services, comparable in size and customer base to WIMA but with limited geographic footprint.

Others

• Kistler Group: Swiss provider of measurement technology including process monitoring and quality inspection sensors; comparable as an industrial measurement ecosystem peer rather than a direct fastener-sorting competitor.
