Electrical and automation cabinets can be manufactured either as individual project deliveries or as long-term contract manufacturing at our facilities in Tampere and Muurame. Order volumes range from small one‑off assemblies to year‑long projects, and several deliveries may progress in parallel. Our production scales quickly according to project requirements and volumes, and continuous development based on the Lean model ensures efficiency, transparency and reliable delivery performance.
Contract manufacturing is ideal for customers who need continuous, long‑term production capacity and stable delivery cycles. We reserve the required capacity in advance, ensuring consistent quality, predictable costs and secure availability even when market conditions fluctuate. This model is well suited for long‑lifecycle products or regularly recurring deliveries.
Project‑based manufacturing is the right choice for unique applications, single cabinet deliveries or large one‑off projects. Each cabinet is manufactured according to project‑specific designs, technical requirements and operating conditions. Lean‑driven production allows us to manage multiple large projects simultaneously, making this model a flexible and reliable option for time‑critical or technically demanding deliveries.
We supply electrical and automation cabinets to a variety of industrial sectors where high quality, precise documentation and reliable delivery performance are essential. We understand the specific requirements of each industry and tailor our solutions accordingly.
We deliver cabinets to the following sectors, among others:
The delivery process of our electrical and automation cabinets is finalized with comprehensive testing and simulation, ensuring flawless functionality before shipment. All cabinets are measured using calibrated instruments, our testers are trained professionals, and every test is documented in a detailed test report.
Factory Acceptance Tests (FAT) can be performed at our facilities using the customer’s own procedures or fully executed by our specialists. FAT testing verifies the system’s functionality in its intended application and helps identify potential functional deviations, such as design‑related issues. FAT accelerates commissioning and reduces project risks by enabling necessary corrections already during the production.
Completed cabinets are also tested at the software and logic level. We offer parameterization, software testing and functional validation essential for commissioning, allowing the cabinets to be delivered as installation‑ready as possible.
Our simulation service enables complete testing of a control or automation function before installation. For example, cabins delivered to shipyards, such as marine auxiliary boiler control cabinets, can be tested in a fully simulated environment that replicates real operating conditions. This allows us to deliver a fully installation‑ready cabinet, shortens project lead times, and ensures reliable system behavior well before on‑site commissioning begins.
Quality management is a fundamental part of our electrical and automation cabinet manufacturing process. It is reflected in design, testing and the components we choose. Every cabinet is manufactured according to certified processes, and each detail is engineered to meet both industrial requirements and customer‑specific quality and safety criteria. Thorough quality assurance ensures that our cabinets operate reliably throughout their lifecycle, whether used in the energy, food, process or marine industries.
Our operations follow the ISO 9001 quality management system, ISO 14001 environmental management system and the ISO 45001 occupational health and safety standard. This certified operating model ensures repeatability, documentation and full traceability throughout the entire manufacturing process. As a result, every cabinet meets both national and international requirements and provides a robust foundation for safe and high‑quality performance.
We use only proven and industry‑trusted components in our electrical and automation cabinets. Component selection is always driven by customer and project requirements, allowing us to implement both standard and application‑specific solutions using trusted, industry‑proven components. Our long‑term partnerships with leading suppliers, including Phoenix Contact, ABB, Siemens and Schneider, ensure long‑term reliability, excellent maintainability and consistent performance in critical industrial applications.
We also maintain extensive component inventories and proactively monitor market changes. This enables us to secure predictable delivery times and keep production running smoothly, both for individual automation cabinet deliveries and large‑scale project batches.
The marine industry imposes exceptionally high requirements on electrical and automation cabinets. In addition to familiar on‑shore regulations, the sector is governed by classification rules designed to ensure vessel safety and operational reliability. We work with several classification societies, including DNV, Bureau Veritas and Lloyd’s Register, and ensure that each cabinet meets their technical and documentation requirements.
Marine applications also demand precise documentation, reliable delivery schedules and the ability to react quickly to project changes. We have delivered cabinets for auxiliary boilers, pumping systems, automation functions and other critical onboard systems. We can also manage the entire classification and compliance process on behalf of the customer, helping streamline the project and accelerate commissioning.
Insta is a UL‑certified manufacturer of electrical and automation cabinets. We design, build and test our cabinets to fully meet North American electrical safety requirements. UL508A certification ensures that every cabinet complies with the relevant North American Electrical Safety standards and can be accepted without additional system‑ or device‑level testing.
The certification covers component selection, wiring and routing, protective devices, enclosure construction and functional testing. We supply UL‑compliant cabinets for a wide range of industrial, process and energy applications, both for new projects and for upgrading existing solutions.
We have delivered numerous UL projects ranging from designing and manufacturing new UL‑compliant cabinets to converting existing IEC cabinets to meet UL508A requirements.
Our electrical and automation cabinet manufacturing goes beyond building cabinets – it is about having an in-depth understanding of diagrams and each customer. Customer-orientation defines our approach – we have the vision to reach solutions that might never even have occurred to you.
Many of our customer relationships are long-term partnerships that are built on trust. Long collaboration guarantees that we know our customers and understand what they want and need. In our operations, we emphasize good partnership, customer-orientation, speed, and flexibility. We have been praised for our agile way of managing resources and orders, ensuring reliable delivery even in demanding industrial environments.
Insta and Valmet have collaborated in the manufacturing of automation cabinets since 2002. Their more than 20‑year partnership is built on high quality, a flexible operating model and open, trust‑based communication that supports Valmet’s demanding industrial requirements.
– We look for partners that we can trust and with whom we can have an open discussion. For us, Insta is a familiar, reliable company: They are a trusted partner that consistently delivers high quality. Whenever there have been issues, we have been able to resolve them constructively. We have been happy to work with Insta for more than 20 years, says Valmet’s Supply Chain Engineer Petri Raiskila.
– It is important to have flexibility and the ability to make quick changes. Sometimes there are situations where manufacturing is ongoing, and you need to be able to stop what you are doing and make a U-turn. Not every company can do this. I would say that this is one of Insta’s strengths.
