I need precise lost-wax / investment casting carried out in Brass, produced in repeat runs of about 100 pieces per batch. Each part weighs between 51-100 grams and must leave your foundry with a consistent, high polish finish straight off the finishing line—minimal secondary work on my end. The parts are small but detail-rich, so dimensional fidelity, clean gating, and pin-free surfaces matter as much as the gloss. I will supply a 3D CAD model (STEP) and can also ship master prints if that streamlines your mold making. You would handle wax tree preparation, shell building, the pour itself, and all post-cast cleanup and polishing. Deliverables per batch • 100 brass castings, 51-100 g each • High polish finish ≤ Ra 0.4 µm, no visible porosity • Dimensional tolerance ±0.1 mm, verified with your QC report • Safe, protective packing ready for courier pickup If your facility already runs small-lot investment casting and in-house polishing, this should slot neatly into your workflow. I’m ready to move ahead as soon as we confirm lead time and shipping logistics.

As a mechanical engineer with proven experience in product development and an expert in SolidWorks, Fusion 360, and other CAD tools - I can assure you of efficiency and precision in every step of the manufacturing process including wax tree preparation, shell building, and casting. I have been involved in numerous projects requiring high-polish finishes, including brass casting where consistency is paramount. I understand the importance of clean gating and pin-free surfaces for small but detail-rich parts. In line with your project description, I utilize DFM principles to ensure cost-effective production whilst maintaining quality. I will deliver the exacting dimensional tolerances of ±0.1 mm with verification through comprehensive QC reports. More so, my background in electromechanical systems ensures that the smaller technicalities required for this project are taken care of. With my 7 years of experience, I have built a solid network with suppliers and shipping companies that would streamline the logistical aspect for a smoother production.

Your focus on high-polish brass casting is impressive. Delivering consistent quality straight from the finishing line is key, especially with parts that require such dimensional fidelity. A common pitfall here is dealing with surface imperfections or inconsistencies in polish, which can lead to costly rework and delays. If any piece falls short, it disrupts the entire batch and impacts your timelines. I'd start by ensuring your 3D CAD model is optimized for mold-making. This is crucial for clean gating and minimizing secondary work. I’ll also implement a rigorous QC process, checking each casting to meet your dimensional tolerances and polish requirements. I’ve handled similar projects, and revisions are built into my process to ensure we hit the mark every time. Do you want to explore the possibility of getting this sorted together? I’m happy to discuss this in a free consultation, even if you decide not to move forward with me.

Hello, I can handle repeat 100-piece brass investment-casting batches, with close attention to fine-detail reproduction, gating, dimensional consistency, surface quality, and final polishing. I can work directly from your STEP model or physical master, covering mold/wax preparation, shell building, casting, cleanup, polishing, and dimensional QC. Target specifications understood: 51–100 g per part, ±0.1 mm tolerance, ≤ Ra 0.4 µm polished finish, and no visible porosity, with protective packing for shipment. Please share the STEP model so I can review geometry, tolerances, and manufacturability before confirming lead time and batch pricing. Thanks.

I bring hands-on investment (lost-wax) casting experience from my time at Boss Scientific, along with ongoing sand casting work at Tampa Brass & Aluminum — so I’m well versed in both casting methods and comfortable managing a brass lost-wax run like this one from wax pattern through final finish. For this batch, I can commit to the process end-to-end: wax tree preparation, shell building, pour, and post-cast cleanup/polishing to hit your Ra 0.4 µm finish and ±0.1 mm tolerance, with a QC report accompanying each batch. I’ll work directly from your STEP file, and can also incorporate master prints if that speeds up mold prep on my end. Turnaround for the first 100-piece batch is 30 days, with a clear path to faster repeat runs once the process is validated. Happy to discuss any specifics on gating or parting lines before locking in tooling.
