What Are Custom Silicone Parts?

Custom silicone parts are non‑standard silicone components manufactured through mold design and vulcanization molding according to customers' specific requirements. They are widely used for sealing, cushioning, insulation, protection, connection and other functional scenarios. Unlike standardized silicone products, they can be fully customized in shape, size, hardness, color and performance based on actual installation space, operating environment and functional requirements, solving the problem that standard parts cannot adapt to personalized applications.

These products cover various forms such as silicone sealing rings, silicone gaskets, silicone feet pads, silicone sleeves, silicone keypads and silicone buffer blocks. Featuring excellent high and low temperature resistance, aging resistance, electrical insulation, food‑grade safety and outstanding elasticity, they are indispensable functional accessories in electronics, medical devices, automotive industry, kitchen appliances, mechanical equipment and other fields.

Key Advantages

Full‑dimensional customization capability
We support full‑process customization from drawings, samples and concept descriptions to finished products. Shape, size, hardness (20‑80 Shore A), color and performance can all be adjusted on demand to achieve truly one‑to‑one product matching.

Superior material performance
We use food‑grade / industrial‑grade fumed silicone rubber and compounded silicone rubber, with a temperature resistance range from ‑60℃ to 250℃. The products feature UV resistance, ozone resistance and chemical corrosion resistance, with a service life far longer than ordinary rubber products.

High‑precision molding process
Adopting compression molding, extrusion molding and liquid silicone injection molding, the dimensional tolerance can be controlled within ±0.05mm, with a smooth and burr‑free surface and high assembly fit.

Environmental safety compliance
Raw materials comply with multiple international standards such as RoHS, REACH, FDA and LFGB. They are non‑toxic and odorless, and can be in direct contact with food and human skin.

Cost‑effective delivery
With an in‑house mold workshop and large‑scale production lines, we realize fast mold opening and high mass production efficiency, effectively reducing customers' comprehensive procurement costs.

Real Customer Testimonials

Mr. Wang, Purchasing Manager of a Smart Home Appliance Enterprise
"We have cooperated with Aobo for three years, and we have always customized our waterproof sealing rings from them. At the beginning, we contacted several factories — either the dimensions were inaccurate and couldn't be installed, or the temperature resistance was insufficient and they aged easily. Aobo's engineers helped us optimize the structure at the very beginning and recommended suitable materials. The sample passed the test at one time. After such a long time of mass production, the batch stability is very good, and there are few defective products. The delivery time is also accurate, and they can help us expedite when we have urgent orders. It's very worry‑free."

Mr. Li, R&D Engineer of a Medical Device Company
"We have extremely high requirements for the biocompatibility and precision of silicone accessories, and we have encountered many pitfalls before. Aobo's medical‑grade silicone materials have complete qualifications, and they can also cooperate with us to conduct biocompatibility testing. The customized silicone sealing plugs have high dimensional accuracy and fit perfectly with our equipment. The one‑time pass rate of quality inspection is over 99%. They have become our core supplier."

Mr. Zhang, Auto Parts Trader
"The biggest fear of doing foreign trade orders is unstable quality and inaccurate delivery. Aobo's custom silicone parts have been exported to Europe for several years, with complete certifications such as RoHS and REACH, and customers feedback that the quality is very good. The most rare thing is the high communication efficiency. Sometimes when customers change the design, they can quickly cooperate with the adjustment, unlike some factories that procrastinate. The cooperation is very smooth and highly recommended."
