Automotive interiors specialist International Automotive Components (IAC) has further expanded its operations in Europe
IAC's newest production facility, at Prestice in the Czech Republic, will initially be producing the company’s injection moulded inner dash, acoustical insulation product for two major vehicle OEM customers – including trunk trim and dash insulation components for the 2016 European Car of the Year, the Opel Astra. however, plans are already in place for the start of a major door trim production programme that will see the plant ramp up to full capacity in 2018.
Marcus Nyman, senior vice-president of IAC’s Cockpit and Overhead Systems business unit, says the 18,000 sq.m facility went from concept to start of production in just eight months. He indicates that a key factor in achieving this compressed timescale was that the new plant replicates an established global set of operational principles and procedures. “IAC operates all of its plants according to the IAC Production System (IPS), which is a lean and integrated process aimed at achieving continuous improvement in all aspects of the business,” he states.

Meanwhile, another important element in the equation, implicit the plant’s formal title, is that it was able to draw on a local resource of labour that was familiar with the company’s way of working, since it is situated just 2km away from the existing Prestice 1 facility, which is the company’s ‘European Centre of Excellence for Overhead Products’.
Accessing a skilled workforceNyman confirms that the close proximity of the two sites is not merely coincidence. “Prestice has an extremely skilled workforce [that has been] ensuring quality and delivery performance on overhead products for decades,” he states. “IAC is the main employer in Prestice, which enables the company to successfully tap into the qualified workforce based in the region while sharing the overheads between the two sites.”

Currently, Nyman confirms, about 80 people are employed at the new facility, though that figure is expected to rise to around 450 as all projected manufacturing programmes kick in. He says that IAC does not disclose the details of investments, but that it spent “several million US dollars” for the greenfield site on which Prestice 2 now stands. He makes a point of adding that his expenditure follows recent European manufacturing extensions in the UK and also the recent start of operations at the company’s first ever South American plant at Itatiaia in Brazil.
The Prestice 2 site produces IAC’s injection-moulded dash inner, which the company says provides an estimated 40% weight reduction compared to a conventional vacuum-formed product. According to Nyman, the process ensures exact, reliable forming of lighter inner dash insulation without any compromise to acoustic performance, and it also delivers more precise mass distribution to match the acoustic hotspots within the component. “At the moment there are three programmes running for injection-moulded inner dash insulation,” says Nyman. “Additionally, Prestice 2 produces the trunk trim parts for the Opel Corsa.” He adds that an “upcoming door programme will be a major platform supporting several variants and derivatives.”

Injection moulding is the key technologyAccording to Nyman the new plant will house four main types of manufacturing process: injection moulding, flame treatment, back-foaming and assembly, but he confirms that IAC regards the injection moulding processes that the plant will operate as the key technology involved. “Injection-moulded dash insulation is genuinely innovative and leverages IAC’s long experience in the IM process,” he says, adding that IAC “operates more than 1,000 injection moulding machines worldwide.”
Nyman says that conventional dash insulation parts are vacuum-formed and that in that process a thermoplastic-based heavy layer sheet is moulded in a tool under vacuum. However, as he further explains, this process has some intrinsic limitations: “The thickness of the part is nearly uniform and a detailed, precise part geometry is difficult to reproduce.”
In contrast, by replacing vacuum forming with injection moulding, using what Nyman describes as “a customised compound with adjusted mechanical, acoustical and rheological properties”, IAC can produce parts that are much more closely targeted to requirements. Quite simply, they are “thicker where more insulation is needed – the so called acoustic hotspots – and thinner where less insulation is required.”
Consequently, the process can simultaneously optimise the acoustic performance of the parts it produces while also reducing their weight. Moreover, says Nyman, doing so does not require any special equipment. “The injection moulding process takes place in standard machines so that the operators can introduce the new technology quickly and flawlessly,” he states.
For the moment Nyman will not be drawn on how the new Prestice 2 facility will develop in the future.
“In agreement with its customers, IAC does not disclose details of its current and future programmes for Prestice 2.” Nevertheless he does indicate that the site is likely to figure significantly in the company’s wider European operations: “The IAC Prestice 2 site is well located to service the central European OEMs in Germany and the Czech Republic, as well in the UK, as far as overhead products are concerned.”
