Casting Parts

AAPICO Maia, S.A. and AAPICO Águeda, S.A., large companies in Portugal, specialize in the production of safety critical components in nodular cast iron, serving primarily the automotive industry in the European market. Over the past years, AAPICO Maia, S.A. and AAPICO Águeda, S.A. have demonstrated technical and environmental excellence, being considered benchmark companies in the foundry industry. These companies are developing and producing lightweight casting solutions, grouped as follows: powertrain (48%), brakes (33%), engine (12%), and suspension (7%). AAPICO Maia, S.A. and AAPICO Águeda, S.A. sell about 26 million components per year.

Foundry process is a millennial process, but always actual. The most common process is the sand mold process. It consists of the usage of pattern plates (tooling) to mold the negative shape of a part to be produced in a sand mold. Liquid melt, obtained in high temperature furnaces, is then poured into the sand mold – filling the entire cavity. After solidification and cooling, the part is removed from the mold, cleaned, and is ready for subsequent operation, such as machining.

AAPICO Maia, S.A. and AAPICO Águeda, S.A. currently supply ductile iron safety critical components to BMW, Daimler Trucks, Ford, Mercedes-Benz, Renault, Stellantis Group, Volkswagen, and as Tier 1 and as Tier 2 to CIE Automotive, Continental, Dana, and Linamar. France, Germany, Hungary, Italy, Slovakia, Spain, and Sweden are among the company’s primary markets in Europe. The company also exports to worldwide markets including America, Asia, and Africa.

Foundry process allows a high production rate with lower cost compared to other production processes. Its major applications are transports (cars, trucks, trains, and boats), machines and equipment, infrastructure, and water systems.

Additionally, foundry is an important industrial process in the circular economy, as it uses steel scrap as main raw material and reuses a considerable amount of the molding sand. Although it uses up an intensive amount of electricity, more advanced foundry companies such as AAPICO are able to obtain a significant part of their energy through renewable sources.

AAPICO advantages rely on experienced team – namely at engineering level – in offering new design solutions and efficiently supporting the foundry. The company can specially highlight the absence of fettling at the finishing line, along with low level of final controls. Also, AAPICO counts on a large data base (more than 5M inputs daily), worked out with artificial intelligence offering a very precise control of the process, granted on the shop floor by the company’s operators.



Assembly Jigs

AAPICO facilities in Ayutthaya province are responsible for the manufacturing of assembly jigs for customers. An assembly jig is an integral part in the production and assembly of automobiles. These assembly jigs are the tools that ensure the accuracy, productivity, and efficiency of car body assembly by precisely attaching each panel to be welded before welding. An assembly jig is a made-to-order product for a specific line of production or model of vehicle. AAPICO provides a full service for the design, manufacture, and installation of jigs—from concept to commissioning—including design, simulation, welding, ergonomics, time studies, and manufacture of tooling. Prior to delivery, a team of engineers conducts assembly trials and validation measurements at the try-out facility. In addition,
the company provides on-site service at the clients’ assembly locations.

The installation and commissioning team have supported customers with bases around the world, including China, India, South America, Southeast Asia, and other countries, with main customers including AAT, Renault, SAIC MG, UD truck and Volvo etc.

With advanced manufacturing process simulation skills and experienced staffs familiar with technical requirements of most OEMs, the company holds a firm competitive advantage over its competitors in the business of manufacturing and supplying of assembly jigs to customers.

Stamping Dies

AAPICO provides a comprehensive range of services, including process stamping design, die design, and production. The company designs, develops, and manufactures normal stamping dies for sheet metal forming applications. The majority of AAPICO’s stamping dies are designed for use in its manufacturing facilities.

The stamping die manufacturing process begins with the creation of a die layout and its simulation in CAE software to form a feasible process and predict potential problems. Then, using CAD computer software, design and sketch the die. For iron casting the die, a foam pattern is made according to the die design drawing, which is then sent to the CNC Machining Center for metal cutting and finishing. Before starting production, the engineering team will perform die trials and improvement as well as quality check.

The company applies two engineering software programs, namely:

1) Auto Form and 2) Pam Stamp for virtual reality simulation of sheet metal formability and to conduct feasibility studies with customers to ensure products’ quality are achievable in accordance with the customer requirements.

The majority of AAPICO’s stamping dies are designed for use in its manufacturing facilities. However, for those that are made for customers, the main customers include Ford, Honda, Isuzu, Mazda, Nissan, Topre, Toyota, and among others.

The company has a long experience of more than 30 years in stamping tandem die class C and B. It’s experience of die-making and die’s standard control have been learnt from many World class OEM car manufacturers.

Today, the company has also acquired additional experience in the transfer of stamping die and ultra-high tensile steel material, along with the acquisition of 3D Laser cut machine which enable the management of turnkey project for the stamping die since the process of prototype sample making up until the mass production stage – all factors of which contributed to the company’s advantage over its competitors.
