Bengbu Longhua Die Casting Machine Co., Ltd. releases professional technical guidelines on speed and pressure matching for precision die casting production, effectively solving common quality defects of thin-walled and thick-walled castings and optimizing the overall performance of die casting machine production. Compactness is the core standard for judging casting quality, and reasonable speed and pressure configuration is the key to stable production of high-quality die casting equipment.
There are differentiated process logics for thin-walled and thick-walled die-cast parts. For thin-walled castings with high surface finish requirements, a fast injection velocity is essential, and conventional die casting machinery speed parameters can basically meet production standards. In contrast, thick-walled castings require both excellent surface quality and internal compactness, which cannot be satisfied by simple high-speed injection alone. After the two-speed nitrogen cylinder explosive injection, traditional machines often suffer from insufficient pressure supplement, resulting in loose internal casting structure and defective products.
Speed and pressure present an inverse proportional relationship in die casting production, similar to vehicle gear operation: low speed delivers strong pressure, while high speed reduces thrust. To address the pain point of insufficient pressure for thick-walled parts, Longhua’s technical team has upgraded the independent supercharging function for its die casting machine. The optimized equipment balances injection speed and supercharging force, greatly improving the internal compactness of thick-walled castings and effectively making up for shrinkage holes and sprue sand holes caused by uncontrolled mold temperature.
Professional equipment, high-precision molds and skilled operators are the three core elements of high-yield die casting production. The optimized speed and pressure matching technology perfectly adapts to diverse production demands of different wall-thickness castings, minimizes product defects, and helps global manufacturing enterprises achieve stable, efficient and high-quality intelligent die casting production.
