How does Wahrheit support international clients with technical service and after-sales support?

Service life can vary according to the equipment model, application and operating conditions. With regular maintenance, our hot melt adhesive machines have an expected operational lifespan of 8–10 years. The actual service life can vary depending on operating intensity and how consistently key maintenance work is carried out, particularly the timely replacement of wearing parts. For this reason, we recommend following the maintenance requirements for the specific equipment rather than treating the 8–10-year figure as a fixed limit.

Our maintenance guidance covers practical checks such as cleaning, temperature inspection, lubrication of moving parts, roller inspection, and replacement of worn or damaged components. We also provide maintenance manuals and technical support for equipment operation and maintenance, while our after-sales service includes equipment inspection and training for daily operation and breakdown handling. Temperature control is another important part of equipment maintenance, as stable heating conditions help reduce excessive heating and glue carbonization. By combining regular maintenance with timely attention to worn components and operating conditions, customers can keep the equipment in proper working condition throughout its expected service life.

We provide hot melt adhesive equipment for a range of industries and production applications, including packaging, hygiene products, furniture, automotive, electronics and non-woven products. Our equipment also supports applications involving medical products, filter manufacturing and general product assembly.

Depending on the customer’s process, we can provide standard equipment or customize components such as spray equipment, coating equipment and control systems. Different industries can have different bonding processes and application requirements, so our product range includes hot melt adhesive machines, spray guns, coating guns and related parts for different production applications. Products are designed to deliver reliable performance in high-speed production lines and are trusted by more than 1000 enterprises across over 60 countries, helping manufacturers achieve efficient, consistent and high-quality adhesive application results. 

To order replacement parts for our hot melt adhesive machines, customers can provide the relevant part specifications or equipment serial number so we can identify the required component and confirm the replacement details. After the part requirements are confirmed, we provide a quotation for the requested replacement parts. Once the quotation is confirmed, the parts are arranged for production or supply and shipment according to the order requirements.

As a manufacturer specializing in hot melt equipment replacement parts, we supply a range of components for hot melt adhesive equipment, including guns, spray guns, glue guns, hoses and scrapers. For customers who need assistance with replacement, our technical team can also provide technical guidance on request. We provide long-term technical support and after-sales service for our hot melt adhesive equipment, so replacement-part support can be connected with the technical assistance required for equipment maintenance.

Wahrheit hot melt machines comply with ISO 9001-2015 quality management certification and CE standards. They also meet relevant EU electrical safety requirements. Before shipping, every unit undergoes strict factory testing.

During production, we follow standardized manufacturing procedures and carry out quality control from raw materials through final delivery. Each machine goes through 110 production processes and 74 inspection processes, followed by multiple tests in our professional testing room. The testing process covers temperature control accuracy, glue supply stability and overall system reliability. We also conduct 7×24-hour aging tests before shipment to further check the equipment.
