Defense Products Manufacturing
Mastars provides end‑to‑end manufacturing for the defense and military sector, from DFM and rapid prototyping through tooling, pilot runs, and high‑volume production, covering plastics, metals, electronics, and testing. Supported by an integrated supply chain and rigorous quality and cost‑control systems, we help customers turn concepts into shippable products and sustain consistent, cross‑batch performance from validation to scaled delivery.
Our stack uses GD&T/CMM + preload for tolerance control; optimizes lead-screw/motor matching via lead compensation and end-point calibration to reduce backlash; suppresses resonance and ensures microstepping linearity for stable trajectories; and applies wear management, thermal drift compensation and SPC for durability. With mature, cost-effective solutions (e.g., roll-forming lead screws), standardized suppliers and full-process control (machining-injection-assembly-EOL), we achieve ~10% cost reduction, 10,000 units/year output, cross-batch consistency, faster time-to-market and maximized yield from NPI to volume production.

Injection Molding
Learn MoreAdditive manufacturing with DMLS produces high‑performance, lightweight metal parts for aerospace and defense, while Mastars also delivers rugged plastic parts via FDM, SLS, and MJF; these methods support prototyping for fit, finish, and function, and in some cases enable bridge and limited‑run production, with multiple finishing options such as post‑machining, painting, and advanced coatings.
High performance and lightweight: DMLS enables complex, topology‑optimized, lightweight structures for aerospace and other high‑demand applications, delivering an excellent strength‑to‑weight ratio.
Rapid iteration and multi‑process coverage: From prototyping to low‑volume production, it supports plastics via FDM/SLS/MJF and metals via DMLS, shortening development and reducing tooling costs.
Manufacturability and surface quality integration: A full path from design optimization to finished parts, including post‑machining, painting, and advanced coatings, ensures performance and appearance.
