Brand Name : MAGTECH INDUSTRIAL CO

Product Description

We provide Flexible Rubber Magnet which is made from bonded ferrite magnet powder, compound rubber, and more. We adopt a fully controlled three-step process of extrusion, rolling, and injection moulding to introduce softness and flexibility in the end product, designed and developed in various shapes as per the client request. Flexibility improves the feature of Rubber Magnet by allowing to bent, twist, coil, punch, and other into any shape without much stress. Moreover, Flexible Rubber can be stick on different types of printing and synthetic papers, metal sheet, PVC, and more. We are highly professional exporter, manufacturer, supplier, distributor, and trader in Hong Kong. Our high quality magnet is available at the market leading rates.

Additional information

Flexible magnets don’t crack or break. Meanwhile the products can absorb shock and sound, so it is good for dc-motor which requires low noise.
Anisotorpic flexible magnet has magnetic properties higher than isotropic flexible magnets (about 30% higher) mainly tailored for dc-motors or strong holding applications. Isotropic flexible magnets are good for promotional, advertising and educational purposes.
Dimension and shape can be in large sheet, large roll, or any size customer prefers. For tailor-made size mould fee ranges from one to several hundred US dollars only.
Self-adhesive backing is available.
Color PVC-laminated flexible magnet available in sheet and roll forms.
Color printing on flexible magnet is available (artwork printed on PVC laminated on the magnet); can tailor cut to preferred shape.
