Custom Master Mold Fabrication service

Design Realized provides custom master mold fabrication services for research, prototyping, and small-batch manufacturing. We help customers create high-precision masters that can be used for PDMS molding, soft lithography, microneedle replication, microfluidic devices, optical structures, and other micro/nano-pattern transfer applications.

What Is Mastering?

Mastering is the process of fabricating a high-quality original mold, also called a master mold, which serves as the template for repeated replication. A well-made master is critical for achieving accurate feature transfer, repeatable molding results, and reliable prototype development.

Our Mastering Capabilities

We provide custom master fabrication using different materials and processes, including:

  • Silicon master molds
  • Metal master molds
  • Microneedle master molds
  • Microchannel and microfluidic masters
  • PDMS replication masters
  • Custom micro-patterned substrates
  • Positive or negative pattern masters

Depending on your design, we can support fabrication methods such as photolithography, etching, laser micromachining, CNC machining, polishing, coating, and replica molding.

Applications

Our mastering service is suitable for:

  • Microneedle arrays
  • PDMS micro-molds
  • Microfluidic chips
  • Lab-on-chip devices
  • Biomedical research devices
  • Drug delivery prototypes
  • Biosensor platforms
  • Optical and surface microstructures
  • Academic and industrial R&D projects

Materials

Available master materials may include:

  • Silicon
  • Stainless steel
  • Nickel
  • Aluminum
  • Quartz
  • Sapphire
  • Resin or polymer-based masters
  • Other custom materials upon request

How to Start

Please send us your drawing or design file, including:

  • CAD file, PDF drawing, or sketch
  • Feature dimensions
  • Overall mold size
  • Required material
  • Quantity
  • Target application
  • Any tolerance or surface finish requirements

Our team will review the design and provide a quotation based on feasibility, material, process, and lead time.

Typical Lead Time

Typical lead time is 2–4 weeks, depending on design complexity, material, and quantity.

Note

All master molds are custom-made. Final pricing and feasibility depend on the actual design, dimensions, tolerances, material selection, and process requirements.
