What SiOCAST SL does

SiOCAST SL is a Barcelona-based industrial technology company founded in 2017 as a spin-off of CONIEX Group to commercialize a patented injection molding process that uses silicone rubber molds instead of traditional metal tooling. The core technology enables manufacturers to go from a 3D CAD file to production-ready plastic parts in days rather than months, with silicone molds lasting 300-500 injection cycles and supporting mold turnaround times of under two hours. The system comprises a fully integrated ecosystem: SiOmaster 3D printing resin for master models (vulcanization-resistant up to 180°C), SiOmold silicone compounds and metallic frames for mold creation, SiOpress vulcanization equipment, SiOform1 (40 cycles/hour) and SiOfuse1 (60 cycles/hour) injection machines, and proprietary SiOres thermoplastic resins in D56, HARD (D64), and CAST variants — the latter achieving a 99.94% burn rate for investment casting.

The company monetizes through a razor/blade model combining capital equipment sales (machines, refurbished units with warranty), proprietary consumables (SiOres resins, SiOmold silicones, color masterbatch), and recurring services including the Service PRO Plan (annual maintenance) and SiOCAST Academy training. Go-to-market is multi-channel: direct sales through siocast.com with demo and quote requests, a dealer/reseller program, and an authorized reseller relationship with Formlabs for 3D printers, plus MMP Capital financing for US customers. SiOCAST serves seven primary verticals — footwear (Alpargatas), tabletop gaming and miniatures (Reaper Miniatures, Corvus Belli, Creature Caster), food-contact chocolate (Chocobreak, Hertog Jan), jewelry and investment casting, technical/engineering parts (Virtual Fly), consumer products (DROP), and product design — with primary verticals being footwear and tabletop gaming. The company holds EU 10/2011 and FDA 21 CFR 175.300 food-contact certifications for SiOres D56, enabling regulated food-grade applications. Operations span Barcelona (HQ, R&D labs, silicone manufacturing plant) and a Little Falls, NJ regional office for North America.

Core offering

SiOCAST SL develops and sells a proprietary injection molding ecosystem that enables plastic part production using silicone rubber molds instead of traditional metal tooling. The company manufactures and sells injection molding machines (SiOform1, SiOfuse1), vulcanization machines (SiOpress), silicone mold systems (SiOmold), proprietary thermoplastic resins (SiOres), and supporting services (Service PRO Plan, SiOCAST Academy). The ecosystem targets manufacturers in footwear, tabletop gaming, chocolate, jewelry, investment casting, and technical parts industries for short-to-mid volume production runs.

Product overview

SiOCAST offers a complete injection molding ecosystem using silicone rubber molds as an alternative to traditional metal tooling. The system centers on three sequential steps: PRINT (3D print master models with SiOmaster resin), MOLD (create silicone molds using SiOmold system with SiOpress vulcanization), and MAKE (inject parts using SiOform1/SiOfuse1 machines with SiOres thermoplastics). Key products include: SiOmold System (silicone compounds, metallic SiOframe frames, tools, and know-how for mold creation lasting 300-500 cycles), SiOCAST machines (SiOform1 at 40 cycles/hr and SiOfuse1 at 60 cycles/hr for injection, SiOpress for vulcanization), SiOres materials (D56 standard resin, D64 HARD for technical parts, CAST56 for investment casting with 99.94% burn rate), SiOmaster 3D print resin, and support services including Service PRO Plan and SiOCAST Academy. Applications span miniatures, wargames, jewelry, chocolate molds, footwear outsoles, technical parts, and action figures.

Scale indicators7 records

Recent moves7 records

Expansion highlights6 records

Emerging players

• Desktop Metal: Public 3D printing company pursuing binder jetting and DLP systems for metal and polymer production. Comparable as a venture-backed alternative-production-technology competitor aiming at the same prototyping-to-production gap that SiOCAST addresses with silicone-mold injection.
• Carbon (a Stratasys company): Digital Light Synthesis 3D printing company targeting end-part production at scale. Emerging competitor to SiOCAST in the production-grade plastics space, with significant venture backing and a different but overlapping approach to eliminating metal tooling.

Broad incumbents

• Sumitomo (SHI) Demag: Specializes in electric and hybrid injection molding machines for precision and medical applications. Comparable to SiOCAST in serving precision plastics and medical/technical parts, though operating at much higher volumes with traditional metal tooling.
• Wittmann Battenfeld: Supplies injection molding machines plus automation and auxiliaries. Compares to SiOCAST as a full-line injection molding equipment vendor; SiOCAST's value proposition competes in lower-volume and rapid-iteration use cases that Wittmann addresses with its small-machine and MicroPower lines.
• Haitian International: World's largest manufacturer of plastic injection molding machines by volume, based in China. Broad incumbent in the same machinery category as SiOCAST; useful for understanding volume-tier competition and Asian market dynamics where SiOCAST has no direct presence.
• Stratasys: Large 3D printing and additive manufacturing company serving prototyping and production. Comparable to SiOCAST in the prototyping-to-production journey but competes with fundamentally different AM-based workflows (FDM, PolyJet) vs. SiOCAST's silicone-mold thermoplastic injection.
• Arburg: Major German manufacturer of injection molding machines across a wide range of clamp forces and industries. Compares to SiOCAST as the dominant incumbent in plastic injection molding equipment; SiOCAST targets the prototyping and short-run niche that Arburg's metal-tooling-centric portfolio underserves.
• Engel Austria: Austrian injection molding machinery manufacturer serving automotive, packaging, and technical molding. Direct comparator to SiOCAST in machine-based plastics manufacturing, differentiated by Engel's high-volume metal-tooling focus vs. SiOCAST's flexible silicone-mold approach.

Direct peers

• Formlabs: US-based SLA/MSLA 3D printer manufacturer and SiOCAST's authorized-reseller partner. Directly comparable as a producer of benchtop-scale manufacturing equipment for prototyping and short-run production; SiOCAST extends Formlabs' PRINT step into a complete MOLD-MAKE workflow using SiOmaster resin.

Others

• VoxelMatters (industrial AM ecosystem reference) / voxeljet AG: German industrial 3D printing systems and services company focused on binder jetting for metal and plastics, including foundries. Comparable as an industrial ecosystem provider that bridges prototyping and short-run production; relevant for SiOCAST's investment-casting customers exploring pattern alternatives to wax.
