High-volume cartridge molding for diagnostic programs

Diagnostic cartridge projects often fail at scale because of sealing issues, tolerance stack-up, warpage, tool maintenance gaps, or unstable molding processes. VEM is structured for high-volume cartridge production, not only prototype molding.

Medical diagnostic cartridge injection molding for molecular diagnostics

Diagnostic cartridge manufacturing capabilities

VEM combines mold design, mold making, molding, validation support and assembly under one manufacturing structure.

Tooling and DFM

DFM review before tool design, mold flow analysis, customer DFM approval, Shenzhen mold making and in-house mold maintenance.

Cleanroom molding

ISO 13485 manufacturing with ISO 7 and ISO 8 cleanroom injection molding in Thailand for medical plastic components.

High-volume production

Programs are best suited for high-volume demand, typically around 1M+ parts per year, with flexibility for selected lower-volume programs.

Complex cartridge features

Experience with multi-chamber designs, tight sealing surfaces, thin walls, small channels, ribs, bosses and snap-fit features.

Materials and overmolding

Typical cartridge materials include PP, with TPE overmolding available where sealing, grip or functional soft-touch features are required.

Assembly and testing

Support for ultrasonic welding, heat staking, laser welding, bonding, packaging, leak testing, dimensional inspection and visual inspection.

From DFM and mold making to validated production

Cartridge programs need early manufacturing input. VEM reviews moldability, material behavior, sealing areas, critical dimensions and production risks before tool design is released.

  • DFM review before tool design
  • Mold flow analysis for process risk reduction
  • Multi-cavity and hot runner tooling
  • In-house mold maintenance and engineering support
  • Transfer tool acceptance for suitable production programs

ISO 13485 quality and validation support

VEM supports medical customers with documented process validation and production quality controls. Requirements are usually defined together with the customer based on product risk, drawing requirements and regulatory expectations.

  • ISO 13485 manufacturing site
  • IQ, OQ and PQ support
  • Process validation support
  • CPK studies
  • Lot and batch traceability through ERP
  • Customer audits welcomed as standard practice
