Production workflow
Every job that enters our workshop follows the same disciplined path. This keeps tolerances tight, lead times predictable, and communication clear from the first enquiry to final dispatch.
Send us your drawings, sample parts, or a rough sketch. We review material requirements, tolerances, and production volumes to confirm feasibility before anything moves forward.
You receive a detailed quote with machining strategy, estimated cycle time, and delivery schedule. Once approved, we lock in the production slot and order any required stock material.
Our programmers convert your model into efficient toolpaths, selecting the right cutters, feeds, and speeds for the material. Fixturing is designed to hold tight tolerances across the full batch.
Parts are machined on calibrated equipment and checked against your specifications. Dimensional reports are recorded for critical features, and surface finish is verified before parts leave the machine.
Completed components are packed and shipped with documentation. If you need adjustments or a repeat order, your files stay on file for quick re-quoting and faster turnaround.
Next Step
Send us your drawings or a rough specification, and our toolmakers will assess the best approach for your component. We respond within one business day with a technical review and a clear timeline.

Client Feedback
Mining, agriculture, food processing and general manufacturing rely on our machining and automation work. Here is what a few of them say.
"Voltronix machined a batch of conveyor sprockets for our packaging line. The tolerances were spot on and the parts dropped straight into the existing assembly without any rework. Their toolmakers clearly understand real production constraints."
Hannes Venter
Maintenance Manager, Agri-Process Foods
"We needed a robotic welding cell for a high-volume frame assembly. Voltronix handled the integration from layout to commissioning. Cycle time dropped by a third and weld consistency is now predictable shift after shift."
Thabo Mokoena
Production Director, Steelcraft Fabricators
"Their CNC turning work on our pump shafts has been flawless. Calibrated equipment and proper inspection reports with every batch. It is rare to find a local shop that documents quality control this thoroughly."

Straight answers about our machining capabilities, lead times, and how we handle custom fabrication work.
Our standard machining tolerance is ±0.01 mm, with the ability to hold ±0.005 mm on critical features using our calibrated 5-axis mills and turning centers. Final inspection is done with CMM equipment, and we provide dimensional reports on request for production runs.
We machine a wide range of metals and plastics, including stainless steel, aluminium, brass, mild steel, and engineering plastics like POM and nylon. For mining and food processing clients, we regularly work with wear-resistant alloys and food-grade stainless grades.
Prototype and single-piece orders usually ship within 5–7 working days. Production batches of 50–500 parts typically take 2–3 weeks depending on complexity and material availability. We confirm exact timelines after reviewing your drawings and quantities.
Yes. Our workshop is set up for flexible batch sizes, from a single validation part to repeat production volumes. We keep the same quality control procedures across every run, so you get consistent parts whether you order one piece or one thousand.
Our toolmakers and engineers review every drawing before machining and flag potential issues with tolerances, material selection, or manufacturability. For bespoke machine building projects, we work from your concept or rough sketch and develop the full mechanical design in-house.
Send us your technical drawings, CAD files, or a detailed description of the part you need. Include material preference, required quantity, and any specific tolerances or surface finishes. We respond with a formal quotation within two working days.
