Each method has its own advantages: single-stage dies yield consistently high product quality but offer low production efficiency, whereas progressive dies provide high efficiency but cannot guarantee the same level of consistent quality; naturally, progressive dies are preferable for mass production.
First, consider the required production volume; progressive dies are recommended for large-scale production. Next, examine the product's design-some designs entail high tooling costs for progressive dies or are simply unsuitable for that process. Finally, take into account your company's stamping press (or injection molding machine) specifications and weigh all these factors together.
