OUR SERVICES
From Design to Mass Production
— All Under One Roof
ZSR is not just a parts supplier. We engineer, prototype, tool and mold your silicone parts in-house, which
means faster lead times and full quality control.
Mold Design & Making
In-house tooling shop with 5,000+ molds built. We design and cut compression, transfer and LSR molds — typically within 7–15 days.
Silicone Compression Molding
Cost-effective molding for solid silicone parts of any size and hardness. Ideal for O-rings, gaskets and low-to-mid volumes.
LSR Injection Molding
Liquid silicone rubber injection for high-precision, high-volume and medical-grade parts. Cleanroom-capable production.
Overmolding & Insert Molding
Silicone bonded to metal, plastic or electronics in a single process — for handles, seals, sensors and assemblies.
Rapid Prototyping
3D-printed, CNC or soft-tool prototypes in days — validate fit, feel and function before you invest in production tooling.
