A Game Changer in the Liquid Injection Molding Industry
A Faster, Cleaner, and More Consistent Way to Produce
ProFill machines and the ProChanger H1 replace manual, inconsistent processes with a controlled, repeatable production workflow designed for precision and efficiency.
Traditional methods often rely on hand filling, makeshift fixtures, or batch setups that introduce variation, slow cycle times, and higher scrap rates. The ProFill machines deliver consistent, pressure-controlled filling with clean changeovers, while the ProChanger H1 automates material handling and transitions that were previously labor-intensive and error-prone. Together, they reduce operator fatigue, improve part-to-part consistency, and significantly increase throughput, allowing manufacturers to scale production confidently without sacrificing quality.

Our Products
Our patented equipment is engineered for repeatable, high-quality output.
Our Services
Precision LSR molding services focused on consistency, quality, and scale.
Sample Runs
Our proprietary liquid injection technology delivers consistent, high-quality parts that let teams validate design, materials, and performance before committing to larger production.
- Produce production-grade sample parts without the cost, tooling, or commitment of full-scale manufacturing
- Validate design, materials, and performance early using Limworks’ proprietary liquid injection technology
- Reduce risk and time to market by testing and refining products before scaling production
Production Runs
Limworks can help develop and produce production volumes of custom silicone parts and seals. Our precision short run molding process is ideal for micro sized parts less than 1cc, shot volumes up to 80 cc and quick turn around production lots from 100 to 10,000 pieces. Just provide a description of your part, size and material to begin the quoting process.
- Deliver consistent, production-grade quality at scale using Limworks’ proprietary liquid injection technology
- Scale seamlessly from sample validation to full production runs. This results in faster turnaround, lower risk, and dependable manufacturing at scale.
- Reduce lead times, risk, and manufacturing complexity with a proven, repeatable production process
Down Packing
Limworks can readily down pack into any cartridge or syringe from any cup (up to 1400mL) or pail (up to 5 gallon). Just provide a description of your material, the material container, type and number of cartridge(s) or syringes(s) to be filled to begin the quoting process.
- Ensure accurate, consistent down packing for market-ready products using Limworks’ specialized equipment
- Reduce material waste and packaging errors while maintaining strict quality standards
- Streamline the final stage of production for faster turnaround and reliable delivery

Applications & Industries
Precision LSR molding for industries that demand consistent, repeatable parts
From gaskets and O-rings to vibration isolation parts, we focus on repeatable dimensions and consistent material performance run after run.
Common applications include valve diaphragms, seals, and soft interface components used in fluid control and device assemblies.
LSR molding supports high-reliability seals, gaskets, and protective parts built for repeatable performance and strict quality expectations.
We can mold rugged LSR parts such as protective boots, gaskets, and sealing interfaces that resist wear, impact, moisture, and contaminants in real-world use.
Electronics often fail at the seams, where moisture, dust, and vibration get in. LIMWORKS produces LSR seals, gaskets, and protective covers that help enclosures stay tight, reduce ingress risk, and protect sensitive components.
Soft-touch grips, overmolded interfaces, and durable silicone components that deliver comfort, durability, and a premium finish without sacrificing consistency in production.
