Soft Tooling Selection and Amortization for Micro Runs
Soft tooling selection balances rapid lead times against progressive cavity wear, requiring direct NRE payment and scrap inflation modeling for micro runs.
Micro Runs
Meaning
Manufacturing strategy focused on the production of very small quantities allows companies to validate designs or serve niche markets without high tooling investments. Organizations utilize micro runs for batches ranging from ten to one hundred units using rapid tooling or additive methods. This approach is common in medical device development and high end automotive prototyping.
It stops being the preferred method once the volume justifies the amortization of a full scale production mold.
Scale Flexibility
Low volume production provides the ability to make design changes between small batches without incurring heavy costs. During micro runs, engineers can test different materials or geometries to optimize the final product. This flexibility is essential for startups navigating the early stages of product development.
Small scale facilities in Shenzhen specialize in these rapid cycles to support the global innovation ecosystem.
Regulatory Burden
Compliance requirements for small batches are often as stringent as those for mass production in the Chinese market. Products produced via micro runs must still meet relevant GB standards for safety and material composition. The State Administration for Market Regulation may require testing for specific categories of consumer goods regardless of the lot size.
Manufacturers must maintain detailed records of the raw materials used to ensure traceability.
Cost Structure
Pricing for these small batches is typically higher on a per unit basis due to the lack of economies of scale. In the context of micro runs, the setup time and engineering labor represent the largest portion of the invoice. These projects are often billed as a service rather than a product sale.
Companies accept this higher unit cost in exchange for the speed and low risk associated with small scale production.
