Independent hot melt service
We bring 30 years of hot melt manufacturing and service experience to Robatech melter, pump and application-head repairs. We investigate heating faults, interrupted adhesive delivery and inconsistent dispensing. Diagnosis, repair and agreed tests form one clearly defined service scope.
Service & supply
We assess deposits, seals and reported heating faults. Send the exact alarm, the affected zone and whether the fault appears during warm-up or production. The adhesive type and equipment configuration determine the assessment: thermoplastic and reactive hot melt applications require separate consideration.
Tanks & meltersWe assess pump wear, contamination and sealing when delivery becomes uneven, stops or leaks appear. The repair scope can include cleaning and replacement of serviceable parts. Identify the pump separately from the melter; its condition and configuration determine the feasible work and agreed delivery checks.
PumpsWe do not repair heated hoses. For a new hose, send the existing reference, length, connections, electrical specifications and temperature-sensor type. The melter and application-head references help confirm selection for the connected system.
Heated hosesWe clean application heads, assess seals and wear, and repair serviceable components. Agreed checks address leakage and dispensing behaviour. We also consider the required application pattern and the reported line conditions to distinguish component faults from process or control-setting issues.
ApplicatorsWe confirm the repair scope, parts selection, cost and lead time for your assembly before work begins.
We bring a manufacturing perspective to every repair: how components are made, where they wear and how they work together. Our expertise spans dispensing modules, applicators, pumps, seals and heated assemblies. This helps us connect a visible fault with the condition of the component and the demands of its application.
After repair, we carry out the agreed bench tests. Depending on the assembly, these cover leak tightness, mechanism operation, adhesive delivery or heating response. The goal is a component prepared for return to service, with a clear scope of work and checks. Installation and commissioning confirm its operation on your production line.
Discuss a repairA melter, its pump and the connected head have separate references. These examples help you prepare a repair or parts enquiry for the right assembly.
These are manufacturer identification examples, not a list of models accepted for repair. STT confirms the scope for the specific unit, its condition and available parts. The source links describe manufacturer products, not STT authorization or endorsement.
Discuss a repairSend the information you already have. We confirm whether the assembly can be assessed, what work is feasible and what is needed before you ship it.
Please agree the receiving address and preparation requirements with STT before shipping equipment. The published business addresses are not automatic repair-delivery instructions.
REPAIR PROCESS
Share the equipment reference, symptoms and available photographs. We clarify the information needed for assessment.
Where inspection is needed, agree shipment and assessment arrangements first. We review condition and repair feasibility.
Confirm proposed work, components, test scope and timing. Any change to the agreed scope needs review.
Carry out the agreed checks, communicate the outcome and arrange return of the assembly.
FAQ
This page concerns hot melt equipment. If your Robatech installation uses cold glue, identify that in the enquiry rather than assuming the same repair scope applies. STT will confirm separately whether the specific assembly can be assessed.
Not before the scope is agreed. Send the alarm information and the references of the connected assemblies first. We will confirm which components are needed and which checks are possible without the production line or its control system.
A useful quotation requires the model, affected assembly and fault description. Parts requirements and feasible testing vary with the configuration. We agree the repair scope, any assessment stage and timing before proceeding.
The affected assembly, extent of wear, parts availability and test scope determine the quotation. Photos and alarm information help prepare the assessment, but internal damage may require inspection. Include your required date. We confirm the assessment stage, repair scope, cost and timing before work begins.
Yes. Send the full Concept variant or AX/SX head designation, the existing part reference and clear photos. We assess parts selection for the specific assembly and application. A family name alone does not establish compatibility or stock; proposed parts, origin and availability are confirmed in the offer.
We agree the checks for the assembly before repair. Depending on its design and the available test setup, these can cover leak tightness, mechanism operation or adhesive delivery. The scope distinguishes bench tests from commissioning on your line with its adhesive, controls and production conditions.
