Custom Plasma Treated Silicone Rollers Adhesion Optimized
Why Choose Plasma-Treated Silicone Rollers
Plasma treatment changes the surface energy of steel, stainless steel, or aluminum cores, allowing the silicone coating to form a stronger chemical and mechanical bond during curing. This is especially important for conveyor rollers that run continuously under load, because it reduces the risk of coating separation and edge lifting over time. The result is a typical peel strength of 2.5 N/mm or higher, which keeps the silicone layer stable on the shaft during long production shifts.
The non-marking silicone compound leaves no residue on cartons, film, or printed materials, helping your customers protect product appearance. After silicone covering, each roller is precision ground to hold run-out tolerance within 0.05 mm for smooth and quiet conveyor operation. We support custom roller diameters from 30 mm to 200 mm, lengths up to 2000 mm, and hardness from 30 to 80 Shore A for different conveying needs.
Typical applications: Packaging lines, logistics sorting equipment, light-to-medium material handling operations, and other smooth conveyor roller systems that benefit from low maintenance, stable coating adhesion, and clean product handling.

About Us
Customers Visiting
Customers from more than 25 countries have visited our factory to review production lines and sample quality before placing wholesale orders. We show real workshops, actual plasma treating stations, and the same grinding processes used for your conveyor rollers. If travel is not possible, we arrange live video calls to walk through the relevant production steps.
As a China‑based manufacturer and OEM/ODM supplier of industrial silicone rollers and elastomer components since 2010, ZHXPRECI serves clients in over 50 countries. We offer customization — from roller hardness (Shore A 30°~80°) to core materials and surface patterns. Our products are tested to meet ISO9001 standards, supporting reliable performance for your conveying, packaging and material handling equipment. Wholesale orders are welcome with competitive direct pricing. We provide expert advice and support from prototype to mass production.
Factory & Equipment
Our facility includes CNC roll preparation machines, plasma treatment units, silicone dispensing and covering stations, curing ovens, and precision grinding centers. We follow a controlled process flow and use measuring tools for hardness, peel strength, dimensions, and concentricity on each batch. This manufacturing structure supports both prototype sampling and volume production for global clients.
Our Certifications (ISO9001, RoHS, Testing Reports)
We operate under the ISO9001 quality management system and can provide material certificates, incoming inspection records, and final test reports for dedicated silicone roller projects. We also support third-party inspection before shipment, and we can reference common market standards such as RoHS and REACH where applicable.
Production & Inventory Policy
Lead time: Actual delivery time may vary due to raw material availability, machine scheduling, and peak season fluctuations. After order confirmation, we provide the most accurate estimate and keep transparent communication.
Stock status: We generally do not hold large finished‑goods inventory, but some popular standard models may have limited dynamic stock (which changes as sales and production progress). Please confirm real‑time availability with our team before ordering.
Bulk & urgent orders: For mass production or tight schedules, we recommend early discussion of capacity and production planning. We will do our best to support your timeline.
Frequently Asked Questions
1. Why is plasma treatment important for silicone rollers?
Silicone naturally has low adhesion to smooth metal. Plasma treatment cleans and activates the roller core, increasing the surface energy so liquid silicone can spread and bond more effectively. This reduces the chance of peeling during high-speed conveyor operation. Our internal adhesion test for plasma-treated silicone rollers typically shows a peel strength of at least 2.5 N/mm.
2. Can you customize the roller size, hardness, and core material?
Yes. We offer custom solutions for outer diameter, roller length, Shore A hardness, and core material including steel, stainless steel, or aluminum. We also support modifications such as flanges, shaft details, and special surface finish requirements. Send us your drawing or samples, and our engineers will provide expert advice based on the actual application.
3. What is your MOQ and ordering process?
The starting quantity depends on roller dimensions and production difficulty. Small trial orders are possible for standard sizes. The typical process begins with a drawing review and sample approval, followed by a commercial quotation, production planning, and final inspection before shipment. We can share a pricing suggestion based on your expected annual volume.
4. How do you maintain consistent quality for continuous high-load applications?
We control each step from incoming raw materials to final grinding. This includes silicone hardness testing, peel force measurement, dimensional inspection, and visual surface checks. For demanding material handling lines, we also recommend dynamic balancing to G2.5 level. These measures help extend service life and prevent unnecessary downtime.
5. Do you offer wholesale pricing, samples, and long-term supply agreements?
We provide wholesale pricing for project-based orders and annual supply contracts. Custom samples are available to verify dimensional accuracy, hardness, and adhesion before mass production. If the project involves high volume, we can design a pricing structure that supports your cost control and keeps delivery planning stable.
6. What is the typical delivery time?
Standard production usually takes 2 to 4 weeks after material and drawing confirmation. Material availability or peak season workload may cause reasonable fluctuations, and we will report the estimated completion date as soon as possible. For urgent maintenance needs, please contact us in advance so we can evaluate an appropriate solution.
