OVERMOLDING, A STATE-OF-THE-ART TECHNICAL PROCESS!

Materials handling is an essential function for industries and warehouses, to efficiently move goods from one place to another. Technological advances and innovations followed one another until the advent of the pallet truck in 1900.

Today, commonly known as pallet trucks or pallet jacks, pallet trucks are used in a wide range of manufacturing industries. Logistics, distribution, retail and any other sector that needs to move heavy loads safely from one place to another, the pallet truck streamlines operations every day, improving productivity and the profitability of product movements.

INNOVATION, PERFORMANCE, SUSTAINABILITY

In 1984, FENWICK, founded in 1862 by Noel FENWICK, was acquired by the LINDE division of the German KION group, one of the world's leading manufacturers of handling equipment, and became FENWICK LINDE.

In 2024, FENWICK LINDE, a major player in materials handling solutions, manufactures, sells and rents around 80 models of industrial handling trucks, pallet trucks and container handlers for moving, loading, transporting, storing, supplying and preparing orders. These products and services are aimed at five main sectors of activity: retail, distribution, transport and logistics, industry and agri-food.

OVERMOLDING EXPERTISE

For this entire range, FENWICK LINDE has chosen to entrust its partner EDELTAMP to manufacture the side rails and short tiller arm for the FENWICK AP N T20-T25 pallet truck.

Featuring a fully-suspended, fold-down platform for a standing self-mounted operator, the driver is protected at all times by fold-down side rails within the truck's frame.

These two armrests, produced in the same steel mold, feature a cast aluminum core overmolded with high-density PU with a hardness of 48 Shore A. A cast aluminum finishing piece painted in Fenwick's RAL 2002 colors is fitted to this structure, using metric screws with dynamometric tightening.

For the short drawbar arm and its protective housing, EDELTAMP chose to manufacture these parts using PA66 reinforced with 50% glass fibers. Injected on a 530-ton press, these parts, which are as hard as steel, require prior operator rework to mill the feeders and the injection point. Prior sanding of the joint faces is also required before the parts can be painted, where the "wet-on-wet" technique between the various primer and finishing coats is used to optimize painting times and costs.

INTERDISCIPLINARY KNOW-HOW

EDELTAMPan expert in high-precision thermoplastic injection molding, stands out for its ability to meet complex technical challenges and co-develop tailor-made solutions with its customers, particularly in the field of plastic injection overmolding. Its mastery of precision plastic injection, coupled with its expertise in overmolding technical parts, makes the company a leader in its field.

This technique is used in a wide range of business sectors where EDELTAMP as a strategic partner. This manufacturing process involves injecting a plastic material onto an existing part to create a new structure. The advantages of overmolding include improved structural integrity, reduced manufacturing costs by avoiding the assembly of multiple parts, and greater design freedom for more complex and ergonomic products.

Thanks to its in-depth knowledge of the constraints associated with thermoplastics, EDELTAMP is able to design critical parts to meet the most stringent requirements of its customers in the agricultural, capital goods, leisure and garden, mobility, construction, wellness, handling and lifting sectors.

EDELTAMP capitalizes on its unique expertise, combining responsiveness, agility and operational excellence, guaranteeing the production of high-quality plastic products, from innovative prototypes to complex technical parts. The company embodies industrial excellence in thermoplastic injection molding, while continuing to project itself towards new challenges on a European scale.
