Liquid-cooled heat sinks live or die by two things: the thermal path between the heat source and the coolant, and the reliability of the metal structure that carries that heat. Cold forging presses attack both problems at once—and they do it without a single weld, braze, or thermal interface between the fins and the base. If you are evaluating manufacturing routes for liquid cold plates, IGBT baseplates, or high-density pin-fin arrays, this page explains exactly where cold forging fits, what the press actually does, and why the process produces thermal performance that extrusion and machining struggle to match.   What Cold Forging Actually Does to Metal Cold forging is a chipless forming process. A metal blank—typically copper or aluminum—is placed in a die cavity and compressed by a press ram at room temperature. The metal flows plastically into the die’s shape, forming features like fins, pins, and bosses in a single stroke or a short sequence of stro...

A hydraulic press only earns money while the ram is moving. The rest of the cycle — carrying blanks in, fishing finished parts out, waiting for a tired operator at 3 a.m. — is where automation pays. This guide walks through the whole integration, in plain engineering language: which feeder to pick, which robot to pick, how the press and robot “shake hands,” how to keep people safe, and how to work out whether it pays back — before you spend anything. Why automate a hydraulic press? Because the press is rarely the slow part. The operator is — and that is not the operator’s fault. Watch a manual press for one hour and time it honestly. The hydraulic stroke itself might take five seconds. Around it sits everything else: walking to the pallet, picking a blank (heavy, oily, sharp-edged), placing it precisely in the die, stepping back, pressing two buttons, waiting, reaching in, pulling the hot or sharp finished part out, inspecting it, stacking...

Choosing a cold forging press by tonnage alone is the most common—and most expensive—mistake in metal forming. A press that is too small stalls mid-stroke and ruins the die. A press that is too large wastes capital and energy while delivering worse control at the low end of its range. The right press sits at the intersection of three variables: tonnage that matches the material’s flow stress, speed that allows the metal to fill the die without cracking, and a die interface that can handle the ejection forces cold forging demands. As a direct manufacturer of custom hydraulic cold forging presses, Goodsjack Hydraulic Machinery works with tool shops, fastener producers, automotive Tier suppliers and export metal formers to match press performance to cold forging process requirements. This practical selection guide focuses on three core decision pillars: tonnage calculation, forming speed control and die-machine matching, written for process engineers, tooling managers and procurement te...

Electric vehicles need battery housings that are light, flame-resistant and affordable at volume. Increasingly, the answer is a thermoset composite: SMC (sheet molding compound) for large covers and trays, and BMC (bulk molding compound) for smaller, thicker, more intricate parts. SMC (Sheet Molding Compound) and BMC (Bulk Molding Compound) are fiber-reinforced composite materials widely used in industrial molding applications. Depending on their formulation and design, they can offer a combination of lightweight construction, electrical insulation, corrosion resistance, and design flexibility. However, producing large, complex battery housings from these materials requires more than a suitable mold. Manufacturers also need reliable molding equipment capable of delivering sufficient pressing force, stable pressure control, and consistent production performance. Large-tonnage hydraulic presses provide an effective solution for demanding SMC/BMC molding applications. At Goodsjack Hy...

Deep-drawn shell components are everywhere: stainless steel cookware liners, EV battery housings, sensor cans, automotive shells, pressure vessels and electronic enclosures. Unlike simple blanking or bending, shell deep drawing demands stable, tunable force, controlled material flow and consistent blank holder pressure. A poorly matched press will create recurring defects — wrinkling, wall thinning, tearing, uneven shell walls and high scrap rates — even with well-made drawing dies. At Goodsjack Hydraulic Machinery, we have spent over 27 years building presses for metal forming applications across the globe. This guide distills what we have learned about selecting a deep drawing press specifically for shell-type components—whether you are producing cookware, lighting housings, motor covers, or similar drawn parts.   The Three Selection Criteria That Actually Matter 1. Structure: Four-Column vs. Frame-Type For shell components, the press structure deter...
