We produce custom steel dies optimized for your part geometry and production volume. Die life is extended by the lower temperatures of hot chamber alloys, and we prove the tooling before any production release.
Metal ingots are melted in a pot integral to the casting machine. Molten metal is injected under pressure into the die, cooled, and ejected in rapid succession, with in-process checks to hold consistent quality across the run.
Each casting is cleaned, deburred, and finished to your specification, then inspected to ISO 9001. We are the importer of record and coordinate freight to your dock with a Certificate of Conformance.

2024 and 6061 are both workhorse aerospace alloys, but they serve opposite needs: 2024 delivers high strength and fatigue resistance under tension, while 6061 offers superior corrosion resistance, weldability, and fabrication versatility.
7075 aluminum nearly doubles the tensile strength of 6061 and dominates aerospace tooling, but it is generally considered non-weldable and harder to form. 6061 offers superior corrosion resistance, weldability, and fabrication versatility for a broader range of industries.
6061 aluminum can be bent, but its precipitation-hardened T6 temper makes it prone to cracking if handled without the right techniques. Proper bend radii, annealing, and controlled heating are all essential for successful results.

Hot chamber die casting is a high-pressure process where the melting pot is built into the casting machine itself. Molten metal is drawn directly from the pot and injected into the die under pressure, allowing rapid cycling. It is suited to low-melting-point alloys such as zinc and tin.
Hot chamber casting works with low-melting-point alloys: zinc, tin, and similar materials. Aluminum cannot be hot chamber cast because it reacts with the machine's metal reservoir.
Fast cycle times, long die life under low-temperature alloys, reduced porosity compared with higher-melt metals, and the ability to cast highly detailed parts with thin walls. These characteristics make it cost effective for recurring production of zinc components.
The process is limited to low-melting-point alloys. Metals that corrode the machine's reservoir, plunger, or cylinders cannot be run in a hot chamber setup. High-melting-point metals such as aluminum are out of scope for hot chamber casting.
Standard production lead time is 4 to 8 weeks, with tooling and first-article timing confirmed at the quote stage. Rush programs can be reviewed case by case.
In hot chamber die casting the injection system sits in the molten metal bath, so metal feeds straight into the die for very fast cycles. It is limited to low-melting-point alloys such as zinc and tin. In cold chamber die casting the metal is melted in a separate furnace and ladled into the shot sleeve for each cycle, which is slower but handles higher-melt metals like aluminum without eroding the injection hardware.
A hot chamber die casting machine combines an integral furnace or melting pot, a gooseneck that channels the molten metal, a plunger that injects it through a nozzle into the steel die, and the die halves with ejector pins that release the solidified part. Because the injection system stays submerged in the melt, the machine cycles quickly and feeds metal with minimal heat loss.
Inconsistent wall thickness is the single most frequent design error across all casting processes. Non-uniform walls cause uneven fill and cooling, which leads to porosity, sink marks, warpage, and crack propagation. Parts designed in CAD for machining or fabrication often fight the casting process at every step. Redstone reviews wall thickness during DFM and runs mold-flow analysis to flag high-porosity areas before any dies are cut.
Porosity is driven by wall-thickness inconsistency, gating design, and alloy or process mismatch. Redstone controls it through DFM wall-thickness review, process capability validation, and, where leak integrity matters, x-ray inspection or leak testing baked into the control plan. For sealed components, vacuum impregnation seals micro-porosity after casting.
Redstone finds issues before parts ship. When something does fail, the response follows a structured sequence: internal triage, a full sort of the affected lot, containment, root cause analysis, and a long-term corrective action to prevent recurrence. Redstone guarantees the parts and will repair, replace, or refund.
