UM supplies and manufactures blow molding spare parts for equipment used to heat preforms, form PET containers and transfer bottles through high-speed production systems. Support is organized by machine brand and component family so maintenance teams can identify the right path for Sidel, Krones and KHS applications.
A rotary stretch blow molding machine depends on coordinated mechanical systems from preform infeed to bottle discharge. In the oven, preforms must be carried and rotated consistently while heating. In the blowing section, molds, stretch mechanisms, cams, valves and station components must operate repeatedly under demanding cycle conditions. Transfer devices then move preforms and finished containers without damaging neck finishes or bottle geometry.
Common blow molding part requests include oven-chain components, spindle-related parts, spindle tips, grippers, cams, rollers, wear plates, bushings, mold supports, stretch-rod components, valves, manifolds and other mechanical items. The exact part families vary by OEM, machine generation, cavity count and configuration.
Some parts are replaced at defined maintenance intervals, while others are changed after inspection reveals wear, play, surface damage or loss of repeatability. A well-defined spare-parts plan should consider both frequent wear items and components whose failure could create an extended shutdown.
When a blow molding part is no longer readily available or cannot be identified through a reference number, UM can evaluate drawings, photographs, measurements or a physical sample. Reverse engineering and 3D scanning may be used when the technical definition must be recreated.
For accurate review, provide the blow molder manufacturer, machine family and the exact assembly where the part is installed. Known OEM references, UM numbers, maintenance manual images and photographs of adjacent components are especially useful.
Also note the container application, required quantity and whether the request is for an immediate repair, preventive stock or a planned overhaul. This context helps separate similar components and determine the most suitable replacement approach.
UM supports replacement parts for major blow molding equipment manufacturers, including machines branded Sidel, Krones, and KHS. Our catalog includes a wide range of aftermarket blow molding spare parts designed for PET production equipment, from preform handling and oven components to blowing stations and bottle transfer systems. If you cannot find a specific part, contact our team at sales@umallette.com with the OEM part number or machine details and we can help verify availability or identify a solution.
Common wear areas include preform transport, oven chains and spindles, grippers, rollers, cams, bushings, guides, valves, stretch mechanisms and mold-support components. Actual wear patterns depend on machine design, operating hours, maintenance practices, lubrication, heat exposure and the containers being produced.
Yes. If a blow molding component is damaged, worn, obsolete, or no longer available from the OEM, UM can evaluate the part for reverse engineering. By using a physical sample, drawing, measurements, or 3D scanning, our engineering team can recreate the component and manufacture a compatible replacement part. This allows customers to restore critical equipment and reduce downtime when standard replacement options are unavailable.
Send us an OEM part number, a drawing, a photo or a sample and our team will confirm availability and compatibility.
