For a reliable PVC/PU conveyor belt splice, we recommend preparing the belt, making a clean and accurately aligned joint, applying controlled heat and pressure, and keeping the splice supported while it cools. The essential setup typically includes measuring and cutting tools, belt clamps, skiving or surface-preparation tools, a compatible splice press, and suitable safety equipment. The exact splice method and machine settings must follow the belt and splice-material manufacturers’ instructions; temperature, pressure, and dwell time are not universal.

Below, we explain what each tool does, how to match equipment to the belt and working environment, and what B2B buyers should confirm before purchasing. For mining and thickener-related operations, we also highlight why belt suitability and site conditions need to be checked alongside the splice equipment.
PVC and PU conveyor belts are thermoplastic products, but belt construction and approved joint designs vary. Depending on the belt specification, splicing may involve a finger joint or another manufacturer-approved configuration. The equipment list should therefore start with the belt data sheet and the splice procedure rather than with a generic machine specification.
A tape measure, straightedge, square, marking tools, and a suitable belt knife help operators establish the joint layout and prepare straight, repeatable cuts. Accurate alignment matters because a skewed or uneven splice can affect belt tracking and joint consistency. For wider belts, buyers should make sure the measuring and alignment method can be used across the full belt width.
Cutting tools must suit the belt construction and the required joint profile. A dedicated cutting guide or template can help maintain consistent geometry, while replaceable blades support clean cuts. Operators should follow the belt maker’s procedure and use guarded tools where applicable.
Some splice designs require removal or shaping of belt layers before joining. A skiving tool, controlled grinding tool, or other approved preparation equipment may be needed for this work. The aim is to produce the specified joint profile without damaging reinforcement or removing more material than the procedure allows.
Keep suitable cleaning materials available to remove dust and residue before the joint is assembled. The belt manufacturer should specify which cleaning products are compatible; an unapproved solvent can affect the belt surface or splice materials. Clean, dry preparation is especially important when work takes place in a damp or dusty processing area.
Belt clamps, locking bars, or a suitable tensioning and alignment arrangement hold the belt ends in position during preparation and joining. They help prevent movement that could change the splice geometry. Select equipment with a working capacity appropriate to the belt width and the forces involved, and verify that it will fit the site’s installation conditions.
A splice press applies the heat and pressure required by the approved joining process. Depending on the system, heating may be provided by a hot plate, hot air, or another controlled heating arrangement. Buyers should confirm the usable working width, heating-zone coverage, temperature control, pressure method, platen design, and compatibility with the required joint profile.
An air-cooled conveyor belt splice press uses airflow to help cool the joint after heating. The press should be evaluated for how it maintains support and pressure during the cooling phase, not only for its heating function. Ask the supplier to clarify the operating sequence, cooling arrangement, required utilities, and process parameters that must be set by the belt manufacturer’s instructions.
Cooling arrangements may include integrated fans or other air-circulation components, depending on the press design. Confirm the available power supply and site conditions before ordering, including voltage, phase, connection type, and any compressed-air requirement. Do not assume that a machine’s electrical configuration will match a plant simply because the press is described as portable.

Temperature and pressure controls should be clear to the operator and appropriate to the process. A timer or documented procedure can help the team follow the specified heating and cooling sequence, but it does not replace training or the belt maker’s parameters. Buyers should ask whether the machine displays actual operating values and how settings are checked or maintained.
In a mining thickener environment, the belt may encounter moisture, abrasive solids, process residues, or cleaning chemicals. These conditions can influence belt selection, joint design, preparation methods, and the practicality of carrying out a splice in place. We recommend confirming the belt material’s suitability for the actual duty before selecting splicing equipment.
For example, use the belt’s real project dimensions when comparing press capacity. A hypothetical project might involve a belt that is 1,000 mm wide and 5 mm thick; these are example inputs only, not a recommended specification for a thickener. The selected press and tooling must accommodate the actual belt width, thickness, joint geometry, and manufacturer-defined process requirements.
Also consider access, ventilation, lifting arrangements, and safe isolation of the conveyor. If the work must be performed on-site, transport weight, setup time, available power, and space around the splice location may influence the equipment choice. Site procedures and applicable safety requirements should determine the necessary protective equipment and work controls.
Before comparing quotations, provide the belt manufacturer and model, belt material, construction, width, thickness, and intended splice design. Include the approved process parameters if available, as well as any restrictions on heating, pressure, or cooling. If the splice method has not been confirmed, ask the belt supplier or a qualified technical representative to clarify it first.
Check the press working dimensions against the widest belt you expect to service, and confirm that its heating and pressure zones cover the required splice area. Review the utilities, control interface, cooling method, portability, and maintenance requirements. For multiple belt sizes or sites, ask whether one configuration can cover the planned range or whether separate tooling is necessary.
Ask suppliers for a clear equipment list, technical specifications, operating instructions, recommended spare parts, and details of operator training or commissioning support where available. Request confirmation of the machine’s configuration against your belt data rather than relying on a general product description. Clarify warranty terms, export packaging, lead time, and the information needed to resolve technical questions after delivery.
At ComiX, we work with B2B buyers to review PVC/PU belt splicing requirements and identify suitable tools or press configurations. Share your belt specifications, splice method, site power details, and project location so we can assess the scope before discussing a solution. Final equipment selection should be confirmed against the belt manufacturer’s requirements and the conditions at your site.
The essential tools for PVC/PU conveyor belt splicing are measuring and cutting tools, belt clamps, suitable surface-preparation equipment, a compatible splice press, process controls, and job-appropriate safety equipment. The right package depends on the specific belt construction and approved splice procedure, so there is no single press setting or universal equipment list for every application. In mining thickener operations, also verify belt suitability for the process environment and practical site conditions.
Your next step is to collect the belt data sheet, splice instructions, belt dimensions, site utility details, and installation constraints. Use that information to request a supplier review and a configuration-specific quotation. ComiX can discuss your requirements and help you evaluate equipment options for your PVC/PU belt splicing project.
