Finnish water pipe fittings for more than 50 years

Heikki Laiho Oy is one of the leading manufacturers of water fittings in the Nordic countries. The family business, founded in 1967, is located in Noormarkku near the town of Pori. More than 50 years of experience, innovative and customer-oriented product development and continuously evolving production methods are the cornerstones of our business, which has made us one of the most important manufacturers of water line fittings, both in the domestic and Nordic markets. We have about 45 employees and our turnover is about 11 million euros.

Our goal is to be a pioneer in the industry in Finland and the products we produce under the HELA brand represent the best in their field. Our product development is always based on the needs of the end user and the basic principle is the absolute functionality of the product under demanding Nordic operating and installation conditions.

HELA products are safe to use

We make products from high quality raw materials. Our main raw material, dezincification-hardened brass, is suitable for use in components of drinking water systems and has been specially developed to prevent corrosion of parts of the water supply network caused by aggressive soil and water in Finland and northern Europe.

In our operations we follow the certified quality system ISO9001:2015. All products subject to national type approval are tested and type approved (STF) by VTT. Fittings and valves for service water systems are not covered by the harmonised product standard, i.e. they cannot be CE-approved and therefore no CE marking is required, but the suitability of the product is demonstrated in Finland by STF type-approval.

We cooperate with the industry's research and testing institutes and HELA products comply with current regulatory requirements.

Functionality. Reliability. Economic efficiency.

Heikki Laiho Oy knows how to combine functionality, reliability and economic efficiency in its products. The cornerstone of our business is the management of the manufacturing process all the way from design to final assembly and packaging. Efficient, highly automated production combined with innovative product development, functional information systems and logistics guarantee the customer the best solution at the right time and at a competitive price.

Investment in production technology and continuous development of the manufacturing process ensures that our products are of the highest quality and economical for our customers. The basis of our product development is a continuous dialogue with customers and end-users, which means that we strive to develop products that are functional, easy to use and at the same time cost-effective.

Specialty products and subcontracting

In addition to standard products, we also manufacture products and parts according to the customer's wishes and own drawings. More than 50 years of experience in the design and manufacture of various brass, aluminium and steel products and very modern and competitive production methods make Heikki Laiho Oy a reputable and reliable subcontractor.

We have several reputable domestic and foreign industrial companies from various industries as our customers. As a full-service subcontractor, we can offer the entire manufacturing process competitively and reliably, from product design and 3D modeling to final assembly and testing.


Our casting method is gravity die casting of brass and aluminium. The piece size generally varies from about 0.2 to 20 kg. The series size varies between 100 and 15 000 pieces. The size of the smallest batch that is profitable to produce depends very much on the piece and must always be assessed on a case-by-case basis. Very multi-shaped pieces can be cast by gravity die-casting. The internal shapes of the product are made with sand cores which can be used to make very complex internal shapes.

We design and manufacture all necessary moulds (ingot moulds) as well as sand core moulds, which enables us to ensure the manufacturability of the product and a successful end result.

Gravity die casting as a casting method provides a fine-grained and dense microstructure through rapid solidification and cooling of the casting metal, and thus good mechanical properties. The parts cast in a metal mould have uniform properties and a good surface quality.

Machine shop

Cast products are processed in our modern and highly automated machine shop. In addition to machining cast products in our own foundry, we also turn and machine various parts and components from brass, steel and HST bars and material tubes. Our versatile machine base enables fast and cost-effective production of complex parts. Loading of all our production machines is carried out by robots with machine vision and production can be run unmanned. The machine range includes several different transfer machines, machining centres with 3, 4 and 5 axis, as well as various lathes and automatic stamping machines.
