Multi-cavity vacuum casting lets you produce multiple parts in a single pour using one silicone mold — cutting unit cost by 30–50% and delivering batches in 1–2 days. Ideal for 50–500 piece trial runs, it outperforms single-cavity casting in efficiency and consistency without the lead time or expense of steel tooling. This guide covers the four-stage workflow, mold design rules, PU material options, and a side-by-side comparison with 3D printing and CNC to help you choose the

FDM 3D printing produces custom mahjong tiles in full color straight off the printer — no molds, no painting, no minimum order limits. This guide covers materials, costs, turnaround times, and use cases to help buyers make informed sourcing decisions.

What is the actual difference between a 2 plate mold and a 3 plate mold in plastic injection molding? While product engineers and buyers often confuse the two, understanding their parting lines, gate positions, and production modes is critical. Read our selection guide to find the perfect match for your design.

Discover 7 practical ways to reduce prototype costs through smarter design, material selection, optimized tolerances, and the right manufacturing process such as CNC machining, 3D printing, or vacuum casting.

This guide compares CNC machining and injection molding in terms of cost, speed, precision, materials, and production volume. Learn when to use CNC for prototyping and low-volume parts, and when injection molding becomes the better choice for mass production.

This article compares sheet metal and 3D printing for functional rapid prototyping, highlighting differences in cost, lead time, material performance and DFM validation. It explains the pros, cons and suitable materials of both processes for structural and thermal testing. It recommends a practical hybrid strategy: use 3D printing for early design fit checks, then sheet metal for real functional verification and production-ready validation to reduce cost and manufacturing ris
