Practical guides on casting, molding and dispensing — for prototyping and low-volume production.
Vacuum Casting Alternative: Low-Pressure Two-Part Dispensing for Low-Volume Parts
Vacuum casting is the standard for low-volume polyurethane parts — but the chamber, degassing, and tooling add cost. Here's where low-pressure two-part dispensing can cover the same ground, and where it can't.
Two-Part A:B Dispensing Explained: Ratio, Mixing, and Why They Matter
Most casting resins, polyurethanes, and silicones come as two parts that only cure once combined. Here's how A:B dispensing works — the ratio, the mix, and the static nozzle that ties them together.
Small-Batch Resin Casting: Throughput, Cost per Part, and Consistency
Past one-off prototypes, small-batch casting becomes a process question. Here's how to think about throughput, the real cost per part, and part-to-part consistency on a production run.
Automated vs. Manual Resin Casting: When to Upgrade From Cups and Scales
Hand mixing two-part resin works — until you need the same result every time. Here's where manual casting is still the right call, and the signals that it's time to automate.
A Future Flovv Update Is Coming: Silicone & Epoxy Capabilities
Flovv casts polyurethane and resin today. A future Flovv update we're developing will bring silicone and epoxy capabilities into one system too. Here's what's coming.
Polyurethane Casting Guide: Methods, Machines and Getting Started
A complete guide to how polyurethane casting works, the available methods, and how to choose the right equipment for prototyping and low-volume production.
How to Cast Polyurethane: A Step-by-Step Process
A practical walkthrough — preparation, mix ratio, pouring and curing — for bubble-reduced, homogeneous and repeatable polyurethane casts.
Polyurethane vs Silicone: Choosing the Right Casting Material
The differences between polyurethane and silicone casting materials — strength, flexibility, cost — and when to choose each for your application.
