Liquid silicone rubber (LSR) molding is ideal for producing flexible, heat-resistant, and biocompatible parts, especially for medical and food-contact applications. It uses a two-part, platinum-cured silicone injected into a heated mold to create precise, flash-controlled parts with excellent durability, chemical resistance, and consistency in medium to high production volumes. What

Replicating obsolete stainless steel machinery parts without drawings requires reverse engineering that restores original design intent, not just copying worn geometry. By combining CMM metrology, contour analysis, and controlled prototyping, engineers can reconstruct precise tolerances, validate fit with 3D mockups, and manufacture durable replacements—often faster and more reliably than sourcing

Rapid tooling services use prototype molds and fast tooling methods to quickly create cost-effective injection molds for testing and low-volume runs, bridging the gap to mass production with real materials and near-production quality parts. They reduce lead time, lower tooling costs, and provide design feedback early, helping teams de-risk full-scale

Plastic injection molding creates custom plastic parts by melting thermoplastic pellets, injecting the melt into a precision steel mold under pressure, cooling it in‑tool, then ejecting a fully formed component. Cycle after cycle, this process repeats with tight control of temperature, pressure, and timing. The result is high‑quality, consistent plastic

You get the best value from cost‑effective CNC machining by simplifying part geometry, standardizing materials and tolerances, and matching order volume to the right supplier strategy. Smart DFM, consolidated operations, and transparent quoting keep rates competitive without compromising quality. A partner like 6CProto blends automation, process control, and experience to

Material certificates and RoHS compliance protect your product by verifying that every metal, plastic, or electronic component meets specified mechanical properties and global substance restrictions. Through lab-tested reports, traceable heat numbers, and documented declarations, manufacturers prove materials are authentic, safe, and compliant, reducing failure risk, customs issues, and liability across

CNC tapping and threading deliver reliable metric and imperial parts by combining precise toolpaths, matched drill sizes, rigid or synchronized spindles, and correct thread standards. When designers specify threads clearly and shops use proper taps, thread mills, and inserts, internal and external threads assemble repeatably, seal correctly, and withstand service

Zinc plating is more cost-effective than anodizing when you require economical corrosion protection on ferrous metals (steel or iron), particularly for high-volume, small-scale components, hidden structural frames, or fasteners used in mild to moderate environments. It provides sacrificial galvanic protection at a fraction of the cost of electrochemical conversion. Conversely,

Micro-milling of complex molds lets engineers cut sub‑millimeter channels with 50‑micron end mills at ultra‑high spindle speeds, achieving excellent dimensional control and low surface roughness for microfluidic diagnostic chips. By combining ultra precision toolpaths, high‑stability machines, and careful tool selection, you can prototype and scale medical diagnostic platforms with reliable

Rapid prototyping de-risks Phase 1 medical device verification by creating CNC‑machined, production‑grade parts that behave like the final device, but are available in days instead of months. Engineering teams can assemble, test, and iterate mechanical designs while documenting verification results under ISO 13485 design controls, before locking tooling, starting clinical

Passivation of stainless steel is a controlled acid treatment that strips away free iron and contaminants left by machining, then allows a chromium-rich oxide film to reform on the surface. By using properly specified citric or nitric acid baths, passivation greatly reduces early surface rusting and preserves the inherent corrosion

Custom knurling improves grip ergonomics by tuning pattern type, pitch, and depth to match hand size, torque needs, and environment. On CNC lathes, properly set form or cut knurling creates repeatable diamond or straight textures without double-tracking. When combined with DIN 82 pitch selection and material-specific pressure control, tool handles
