Solid Silicone & LSR — Two Processes, One Factory
Most silicone suppliers specialize in one process. CYES runs both under the same roof, so we can recommend the process that actually fits your part — not just the one we happen to own.
| Process | Best for | Typical tooling |
|---|---|---|
| Solid silicone compression molding | Gaskets, seals, kitchenware, thick or large parts, low-to-mid volume | Multi-cavity compression molds, 20–500 t presses |
| Liquid Silicone Rubber (LSR) injection molding | High-volume, tight-tolerance, medical and sealing parts | Cold-runner molds, up to 64 cavities |
Beyond these two core processes we also run silicone extrusion and die-cutting for tubes, cords, profiles, gaskets and washers.
In-House Mold Making and Development
Molds are the single biggest lever on part quality, cycle time and cost. CYES builds its own molds in-house, which shortens lead times and keeps design intent intact from CAD to finished part.
CNC Milling
MAKINO 24,000 RPM spindles hold mold cavities to ±0.01 mm.
Mirror EDM
Mitsubishi mirror EDM delivers mirror finish and ±0.005 mm fine features.
CMM Verification
HEXAGON Global S CMM verifies mold cavities and electrodes before steel is hardened.
This tooling capability is documented in detail on our Tooling & Engineering and Silicone Mold Making pages.
Machines and Brands We Run
A named machine list is what a real buyer checks. Here is the molding and tooling fleet we actually operate.
| Category | Equipment / brands |
|---|---|
| LSR injection molding | YIZUMI UN120LSR / UN160LSR, ENGEL victory LSR 100, BOY LSR 55 E, Techen JCLS-400-15 |
| Solid compression molding | Multi-ton compression presses, 20–500 t, with automated pre-forming |
| CNC milling | MAKINO 24,000 RPM spindles |
| EDM | Mitsubishi mirror EDM |
| Measurement | HEXAGON Global S CMM |
| Cleanroom | ISO Class 7 cleanroom for medical and high-purity molding |

A 10,000 m² Facility, 200+ People
Our factory spans 10,000 m² and houses mold making, compression and LSR molding, post-curing, assembly and a dedicated QC laboratory in one continuous flow.
More than 200 skilled staff work across engineering, tooling, molding, QC and project management. One dedicated team follows each project from first sample to long-term supply, so buyers always have a single point of contact.
Over 100,000 molds have been built in-house since 2004, and 1,000+ distinct OEM/ODM projects delivered for customers in 50+ countries. Each project is counted once, regardless of repeat orders, SKU variants or customer relationships.

- ISO 45001 — Occupational Health & Safety
- ISO 13485 — Medical Devices Quality Management
- SEDEX SMETA / BSCI — Social Responsibility Audit
Material & product compliance (third-party tests)
- FDA 21 CFR 177.2600 — food contact (USA)
- LFGB — food contact (Germany / EU)
- RoHS / REACH — restricted substances (EU)
- USP Class VI / ISO 10993 — biocompatibility (medical)

OEM / ODM Cooperation Process
| Step | Stage | What happens |
|---|---|---|
| 1 | Inquiry & DFM | Send a drawing, 3D file or sample. Our engineers review it and return a design-for-manufacturing report within 24 hours. |
| 2 | Prototype | Rapid prototype in 1–3 days to validate fit, feel and function before tooling. |
| 3 | Mold making | In-house single-cavity mold in 7–15 days; multi-cavity tooling quoted to spec. |
| 4 | Sample & validation | First-article samples with dimensional and material test reports for your approval. |
| 5 | Mass production | EVT → DVT → PVT progression with in-process and final QC at every stage. |
| 6 | Delivery & aftercare | Ship on schedule with compliance documents; engineering support continues for life of the program. |
