Custom Automotive Molds
with Mastars
Backed by extensive injection molding services and overmolding options,
we craft top-tier molds tailored to various automotive brands.
Custom Automotive Parts Manufacturing
Auto parts mould (also called automotive parts mould) is specialized tooling for manufacturing automotive components—shaping plastic/metal parts like body panels, interior parts, and engine components.
Mastars provides precision-engineered automotive components spanning interior trims to under-the-hood parts, leveraging custom injection molding expertise to meet the automotive industry’s strict dimensional tolerances, durability demands, and regulatory standards. Collaborating closely with OEMs and tiered suppliers for new vehicle development or design upgrades, we deliver high-performance plastic parts that integrate seamlessly into complex assemblies—backed by advanced tooling, rigorous quality control, and fast turnaround to accelerate production timelines without quality compromises.

Material Options
Polypropylene (propylene polymer): chemical/UV/water-resistant, used for car bumpers.
PVC accounts for ~16% of car plastic components. Flexible and heat-resistant, it’s used for auto hard/soft parts (interior panels, dashboard components).
Polyurethane (PU) is used for products needing high flexibility—plus auto seals, gaskets, insulation panels, and suspension bushings.
Polycarbonate (PC) is a rigid, hard, durable material—its heat and weather resistance makes it ideal for car bumpers.
Polyamide (Nylon), being wear-resistant, is used to make bushes and bearings.
