Silicone is famours for their durability, so silicone NSF valve can withstand repeated use and are resistant to wear and tear.

4. Low MOQ

Hopewell provides silicone valves at high quality, low MOQ and factory price.

5. High Precision

The tolerance of the curved wall thickness of silicone slit valves is controlled within 0.03mm, the dispensing angle is controlled within 30 degrees, zero clearance and non stick slit cut.

6. One-piece Design

Silicone slit valves can directly be assemble with inverted plastic squeeze bottles, no need plastic valve seats.

The Advantages of Hopewell to Produce Silicone Valves

1. Our factory is established in 2009, specializing in the research and development as well as production of silicone rubber products. With over a decade of experience, we have built a strong reputation in industry of silicone molding. 

2. Our production facilities span over 6,000 square meters and include a 100,000 clean production workshop and a surface treatment workshop. 

3. With in-house precision mold design and mold making department. 

4. High-precision mold processing equipment imported from abroad has stable quality and the slit cut size can be controlled within ±0.05MM, effectively eliminating the tilt of the liquid outlet angle caused by eccentricity.

5. Independently developed automated silicone valve punching equipment, incision, appearance, and opening confirmation are all completed on one machine. In case of abnormal opening, the equipment will automatically alarm and shut down, ensuring 100% incision quality.

6. All our silicone valves use an AOI (Automated Optical Instrument) for quality inspection, which can confirm all defective contents such as burrs, missing flushes, missing materials, bubbles, etc. one by one, and automatically reject defective products.
