Our white polyurethane (PU) timing belts utilise high-strength steel or Kevlar cords as the tensile layer, ensuring excellent dimensional stability. Depending on customer requirements, hollow cleats or profiles are incorporated into the surface via hot-melt welding or an integrated moulding process. This unique hollow design not only reduces the overall weight of the belt but, more importantly, provides physical channels for vacuum-assisted conveyance, sensor detection or the installation of auxiliary fixtures, making it a key component in achieving complex automated material handling.

Key Advantages and Solutions
Enabling Vacuum Conveying: This is the primary function of hollow bosses. Through the through-holes in the centre of the bosses (or their gaps), in conjunction with the vacuum chamber at the base of the conveyor, lightweight, smooth or slippery materials (such as films, paper, small electronic components and pharmaceutical blister packs) can be securely held in place, enabling high-speed, stable vertical or inclined conveying.
Non-contact Support and Positioning: The studs ‘lift’ the materials, reducing the contact area between the materials and the base belt surface. This effectively prevents scratches on the surface of sensitive materials and ensures precise spacing between items through the precise spacing of the studs.
Functioning as an Attachment Base: The hollow structure allows users to utilise it as a mounting point for small fixtures, sensor probes or alignment devices, enhancing the flexibility of system design.
Reduced System Inertia: Compared to solid bosses, the hollow structure significantly reduces the overall weight of the belt, minimising inertia during frequent starts and stops in the conveying system, thereby improving overall operational efficiency and reducing energy consumption.
Applications
Electronics and Semiconductor Manufacturing: High-speed, mark-free vacuum-assisted handling of precision wafers, PCBs and small electronic components.
Packaging Machinery: Spaced conveying of cardboard sheets in automatic packaging machines, and inverted or inclined vacuum-lift handling of lightweight packaging bags.
Medical and Healthcare Products: Clean conveying of pharmaceutical blister packs, test vials and hygiene products, utilising hollow bosses for the installation of detection sensors.
Solar Photovoltaics: Non-contact conveying during silicon wafer handling and module assembly for solar cells.
FAQ
Q: What is the weld strength of the hollow bosses? Will they detach under vacuum pressure?
A: We utilise state-of-the-art hot melt welding technology. The boss and the base strip fuse at a molecular level at the melting point, and the weld strength often exceeds the tensile strength of the boss material itself. Under normal vacuum loads, the bosses are extremely secure and will not detach or become misaligned.
Q: Can we customise the shape and bore diameter of the hollow bosses?
A: Absolutely. We possess strong mould design and machining capabilities. Whether it is a through-hole or a blind hole, a circular hole or a custom-shaped hole, we can produce customised parts based on your drawings or samples.
Q: Does this white PU belt meet food-grade requirements?
we can provide it. If you intend to use it for food packaging or in the pharmaceutical industry, please let us know. We can supply manufactured using raw materials that comply with FDA (US Food and Drug Administration) or EU (European Union) food contact material regulations.
