Production process

Production

From semi-finished parts to final testing: an industrial process controlled at every stage, in Italy and at our offshore plants.

We leave the production configuration to the customer, offshore or Italian. The product stays the same, and so does the quality.
01

Manifolds

Four key stages, from machining to packaging.

100% testedOEMMade in Italy / Offshore Production
Produzione Manifolds Simplex
  • 01

    Machining of semi-finished parts

    Production starts with the machining of plastic and metal components: flow meters with brass or plastic body, M30x1.5 inserts, fill/drain valves and mounting brackets. Every element undergoes rigorous, continuous quality controls throughout the process, to ensure precision, reliability and compliance with the required technical standards.

  • 02

    Assembly

    Manifold assembly takes place in Italy or, on request, directly at our offshore plants. In both configurations Simplex fully manages the process, ensuring that materials, design and quality standards remain unchanged and perfectly aligned with the original specifications.

  • 03

    100% testing

    Every manifold is tested individually through a compressed-air testing system. High-sensitivity leak detectors identify even micro-leaks, ensuring total control and immediate detection of any potential defect before it reaches the market.

  • 04

    Packaging and customization

    The final stage prepares the product according to the packaging and labelling specifications required by the customer. We use robust packaging designed for maximum protection during transport worldwide, plus fully customized solutions, including colour packaging with customer OEM branding.

02

Accessories

Moulding, assembly and testing of manifold components.

Produzione Accessories Simplex
  • 01

    Machining of semi-finished parts

    Production starts with the machining of plastic and metal components that make up each manifold accessory. For flow meters we mould each element using exclusively selected polymers. For brass components such as inserts, we use top-quality raw materials, combined with EPDM PEROX O-rings and gaskets, with high compression set even in extreme conditions, at high and low temperatures.

  • 02

    Assembly

    Accessory assembly takes place directly at our production plants. Simplex internally manages and coordinates the entire process, ensuring quality consistency, build precision and compliance with the defined technical standards.

  • 03

    100% testing

    Accessories mounted on manifolds are 100% tested with compressed air and high-sensitivity leak detectors to identify any micro-leaks. Accessories sold individually undergo 100% individual testing, ensuring maximum reliability for the end customer.

  • 04

    Packaging and customization

    The final stage prepares the product according to the customer's packaging and labelling specifications. We use robust packaging for maximum protection during global transport, with fully customized solutions, including colour packaging with OEM branding.

03

Actuators

Wax core, automated assembly and electronic testing.

Produzione Actuators Simplex
  • 01

    Machining and sourcing

    The process starts with the machining and selection of components. We produce the wax element in-house, the functional heart of the actuator, responsible for the movement of the piston. Alongside this, we source strategic components such as micro-switches, electrical cables, springs and gaskets, plus in-house production of plastic and metal parts.

  • 02

    Automated assembly

    Actuator assembly takes place through automated processes within our plants, entirely managed and coordinated by Simplex. This approach enables high precision, process repeatability and consistent quality standards on every unit.

  • 03

    100% testing

    Every actuator undergoes a complete electronic check. The test verifies correct operation and, in models with a micro-switch, also checks that activation occurs at the expected time and manner, ensuring operational reliability and compliance with specifications.

  • 04

    Customization and packaging

    The final stage covers product customization, with the customer logo applied on request, and packaging preparation to specification. We use robust packaging for global shipping, with customizable solutions, including colour packaging and internal components with OEM branding.

04

Pipes

Selected raw material, extrusion and quality control.

100% testedOEMMade in Italy / Offshore Production
Produzione Pipes Simplex
  • 01

    Raw material sourcing

    Production starts with the selection of the raw material, supplied by a partner compounder we have collaborated with for years. This collaboration guarantees high quality standards, consistent material performance and fast, reliable lead times.

  • 02

    Extrusion and production

    The production phase involves extruding our pipes: PEX-A EVOH in 3 and 5 layers, second-generation PERT EVOH, PEX-AL-PEX and PERT-AL-PERT. Every batch undergoes sample testing during the process. Pipes are made to customer specifications, for colour, markings and technical identifications.

  • 03

    Analysis and quality control

    Sample analyses are carried out on every batch to verify the correct degree of cross-linking of the material and pressure resistance. These controls ensure high performance and compliance with the standards required for radiant and hydronic systems.

  • 04

    Packaging and customization

    The final stage covers packaging and customization. We offer cardboard box packaging with custom logo or transparent film wrapping, also customizable. External labels are made to specific request, consistent with the customer's OEM identity.

Frequently asked questions about OEM manufacturing

What does contract manufacturing mean for hydronic components?

It means Simplex produces items intended to be sold under the customer's own brand. We handle semi-finished part machining, assembly, testing and packaging in house, so the customer receives a finished, already branded product. This is how we work with European OEMs.

Is production carried out in Italy or abroad?

Both configurations are possible and the choice stays with the customer. Manifold assembly takes place in Italy or, on request, at our partner plants abroad. In either case Simplex manages the whole process, so materials, design and quality standards remain unchanged.

Can components be branded with our logo?

Yes, branding with the customer's own mark is part of the OEM service. We apply the customer logo to actuators on request and produce colour packaging carrying OEM branding, with outer labels made to specification.

Can the packaging be customised?

Yes. We prepare the product to the packaging and labelling specification requested, using robust packaging designed to protect goods in transit worldwide. For pipe we offer cardboard boxes with a custom logo or transparent film solutions, which can also be personalised.

Which technical features can be customised?

Customisation goes beyond appearance. On actuators we can change the stroke and the opening and closing times; on fittings we produce versions for non-standard pipe sizes such as 17x2.2; on pipe we define colour, marking and technical identification to the customer's specification.

Do you make dedicated moulds for a single customer?

Yes. We design and build moulds for plastic components, including moulds held exclusively for one customer. Each mould starts from a preliminary study of the part, the mould flow and the plastic material to be used, and is built for either hydraulic or electric presses.

How does a new product get developed for a customer?

Through our Research and Development department, working closely with customers and partners. Every development starts from listening to the market and turns into a technical answer tailored to the individual project. The starting point is a conversation with our Technical Sales Management.

How does logistics work for an export customer?

Our team handles all import and export paperwork; the customer only needs to arrange collection from our centralised warehouse in Trofarello, Italy, which ships and dispatches worldwide. We also operate an in-house bonded warehouse and VAT warehouse.
