Company descriptions and product listings suggest that its customer base includes producers of plastic pipes, films, cables, profiles, modification compounds, and related industrial materials. Industry listings also indicate use in sectors beyond plastics, including food and pharmaceutical processing, although plastics remains the company’s core market.
Products and Technologies
WALTHMAC’s best-known product category is its online ultrasonic thickness measuring system, used to monitor pipe wall thickness and concentricity during production. These systems are intended to provide continuous feedback on pipe quality, combining sensor hardware and software for data processing, recording, and process adjustment. In plastics extrusion, such systems are important because wall-thickness deviations can affect pressure resistance, material usage, and final product compliance.
Its gravimetric control system and related weight-per-meter control products are designed to maintain stable output by measuring mass flow and adjusting feeding conditions in real time. This type of control is particularly relevant for pipe extrusion, where maintaining constant weight per unit length is critical to material efficiency and dimensional consistency.
The company also offers gravimetric blenders and dosing feeders, including equipment for precise mixing of base resin, color masterbatch, and additives. In industrial terms, gravimetric blending helps ensure formulation accuracy and repeatability, which are essential in applications that require consistent color, mechanical properties, and processing behavior.
A further product area is material conveying, including vacuum conveying and centralized raw material handling. These systems are commonly used in plastics plants to transport pellets, powders, and additives from storage to processing equipment with reduced contamination and labor intensity.
The company’s technical materials also mention broader capabilities in:
- Powder blending
- Pipe production control
- Wall-thickness measurement for plastic pipe
- Industrial automation and control systems
One company statement describes the manufacturing process for its loss-in-weight feeders, noting the main components as a hopper, weighing hopper, discharge mechanism, drive system, and control system. This is consistent with standard industrial feeder architecture used for accurate metering of powders and granules.
Applications and End Markets
WALTHMAC’s principal application area is plastic pipe production, especially for gas and water supply/drainage pipes. The company’s materials repeatedly emphasize pipe wall-thickness monitoring and weight-per-meter control, indicating a strong specialization in extrusion-line quality assurance.
Other stated application areas include:
- Plastic film
- Cable and wire-related plastics
