Silicone Conveyor Belt

SHUNNAI Silicone Conveyor Belt uses advanced coating, lamination and high-temperature vulcanization processes to ensure strong bonding between silicone cover and carcass. The -Si-O- molecular structure of silicone provides excellent resistance against heat, ozone aging and environmental changes. 

From continuous baking ovens and chocolate production lines to pharmaceutical transfer systems and precision electronic manufacturing, SHUNNAI helps customers improve conveying reliability while reducing downtime caused by belt replacement and cleaning.

Solving Production Problems Caused by Sticky Materials

Smooth Release Surface

In food processing and industrial production, material adhesion directly affects production efficiency. Sugar syrup, chocolate, dough, oil-based products and adhesive materials can easily stick to ordinary belt surfaces, causing product deformation and increasing cleaning frequency.

The silicone surface of SHUNNAI belts has low surface energy, allowing products to separate smoothly after conveying. This release performance helps protect fragile products such as biscuits, pastries and confectionery while reducing residue accumulation during continuous operation.

Less Cleaning Interruption

Frequent belt cleaning means additional labor and production downtime. Silicone material does not easily absorb oil, moisture or food residue. The smooth surface allows cleaning with water, steam or mild detergents, helping factories maintain hygienic production conditions with shorter cleaning cycles.

Stable Performance During Temperature Changes

Hot and Cold Working Conditions

Many industries require conveyors to move products between different temperature zones. Ordinary belts may become hard and brittle in freezing environments or soften after long exposure to heat.

SHUNNAI Silicone Conveyor Belts maintain flexibility from approximately -70℃ to +280℃ depending on structure and application requirements. This makes them suitable for applications involving freezing, heating, baking and cooling processes where stable belt movement is required.

Reduced Thermal Deformation

Continuous temperature changes can cause belt stretching, shrinking and tracking problems. SHUNNAI combines silicone coating technology with high-strength reinforcement fabrics to improve dimensional stability, reducing frequent tension adjustment and helping equipment maintain consistent operation.

Clean Conveying for Sensitive Industries

Food Processing Requirements

Food production lines require materials that are safe, hygienic and easy to maintain. SHUNNAI silicone belts comply with FDA food contact requirements and support GB4806 related food safety standards. The dense silicone surface reduces residue retention and supports applications including bread, biscuit, chocolate, fruit and vegetable processing.

Precision Manufacturing Applications

In electronics, pharmaceutical and medical industries, contamination control is essential. Silicone materials provide good chemical stability and do not easily react with cleaning agents. For static-sensitive production environments, SHUNNAI can provide anti-static silicone belt structures to support clean manufacturing requirements.

Customization for Different Equipment Designs

Surface and Structure Options

Different production processes require different belt structures. SHUNNAI provides customized silicone solutions including smooth surfaces, textured surfaces, perforated designs and special edge processing. These options allow the belt to match different conveying speeds, product shapes and equipment layouts.

Additional Components

To improve conveying accuracy, SHUNNAI supports guide strips, sidewalls, perforations and customized splice methods. These designs help prevent product movement, improve positioning accuracy and adapt to complex conveyor routes.

Application Experience Across Industries

Baking and Confectionery Lines

Freshly baked products and sugar-based materials require excellent release performance. SHUNNAI silicone belts help reduce sticking problems in biscuit, cake and chocolate production while maintaining stable performance under continuous oven temperatures.

Pharmaceutical and Medical Production

For tablet, capsule and medical packaging conveying, the belt surface must support clean operation and repeated sanitation. Silicone belts provide smooth transportation and resistance to common cleaning processes.

Electronics and Automotive Manufacturing

Silicone Conveyor Belts are used in precision assembly, component transfer and high-temperature processing applications where stable dimensions and surface protection are required.

Customer Applications

A Food Processing Company in China

“Before using SHUNNAI silicone belts, chocolate residue accumulated quickly and required frequent cleaning. After replacement, the belt surface released products much more smoothly, cleaning time was reduced, and production efficiency improved.”

A Pharmaceutical Equipment Manufacturer

“The production line required a belt that could withstand repeated cleaning and maintain stable dimensions. SHUNNAI customized the silicone belt according to our equipment size, and the running performance has remained stable.”

Silicone Belt Compared with Other Conveyor Materials

FAQ

What temperature range can silicone conveyor belts handle?

SHUNNAI silicone belts can be designed for applications from approximately -70℃ to +280℃. The actual temperature range depends on belt structure, working time and production conditions.

Are silicone belts suitable for direct food contact?

Yes. SHUNNAI provides food-grade silicone solutions complying with FDA requirements and supporting food contact applications such as baking, confectionery and food processing.

Why does silicone release sticky products better than ordinary belts?

Silicone has low surface energy, which reduces adhesion between the belt surface and sticky materials such as syrup, chocolate and dough, making product release easier.

Can silicone belts be customized for existing machines?

Yes. SHUNNAI supports customized width, thickness, surface pattern, perforation, guide strips, sidewalls and splice methods according to customer equipment requirements.
