Hot forging presses are also used in the fashion industry manufacturing.

The worldwide fashion sector is characterized by extremely significant business volumes: around 3 thousand billion euros and it employs 50 million people.

Italy is one of main districts for the fashion industry with historic brands and production chains deeply rooted in the territory.

The sector is affected by global uncertainties linked to inflation, geopolitical tensions, post-Covid recovery but double-digit growth is estimated in the coming years. The increase in business volume is possible thanks to a high dynamism full of creativity and style which canalizes an important flow of news and innovations every season.

The digitalization of sales channels and operational departments and the near-shoring approach have created the need to make the manufacturing process increasingly productive and efficient.

Metals hot forging is a key operation to characterize fashion products and accessories. The logos of the major brands applied on bags, shoes, clothes and belts are made through hot forging and then finished with other downstream processes.

Mecolpress has been the protagonist of this continuous growth process, offering technologically advanced forging solutions with the aim of:

• Increasing production capacity up to 1500 pieces per hour;
• Reducing machine downtimes due to maintenance and tool changes (availability >95%);
• Reducing the consumption of materials, energy and CO2 emissions by 50% (GREEN TECHNOLOGY Industry 5.0);
• Allowing the digital communication between production line and company system and remote diagnostic access (Industry 4.0);
• Flexibility in forging products of different sizes and materials (steel/brass/aluminium);
• Increasing the safety of the production line by reducing human intervention (industry 5.0).

TDS Electrical Torque-Driven Screw presses

TDS Electrical Torque-Driven Screw presses result to be particularly suitable for the hot forging of parts destined to fashion sector.

Here below the 4 strong points that make many customers to prefer these hot forging screw presses:

1. Cycle time does not dependent on forging energy => always optimized productivity
2. Reduction of friction parts => less maintenance and less energy consumption
3. Flexibility in energy settings => production flexibility for product size and type of material (brass, steel, aluminium) and reduction in dies wear
4. Energy recovery of braking energy => reduction in energy consumption

Complete forging lines integration

Even in the fashion sector, the frequent request is to have complete forging lines.

We can supply the line following the customer need, so in addition to the hot forging press, we integrate the cutting, heating, forging and deburring of the forged pieces.

The presses for forging of parts destined to fashion sector have to optimize the process phases:

Automation of machine loading and unloading

We underlined the importance of automating the loading and unloading phases of pieces. The presses must include certain solutions to guarantee maximum performance:

• High-speed Cartesian systems for heated material loading.
• Flexible anthropomorphic robots for heated material loading.
• Unloading of the forged product via air blow to avoid sliding and contact defects.
• Folding of the material to be forged to have a shape as close as possible to the forged parts and to reduce material consumption.
• Possibility of different shapes of the starting material from the traditional round billet to customized shapes (letters, symbols, …).

Productive process data control system

An important solution to take into consideration to start a successful hot forging project for parts in the fashion sector is certainly to equip yourself with a control system of the productive process.

Mecolpress Calipso Software allows to monitor and to adjust the data connected to forging process, and it presents numerous advantages, among which:

• Based on HMI architecture complete with touch screen display
• Functioning parameters of the press and of the auxiliaries that can be inserted from the display.
• For each forging cycle, the main parameters are saved for collection and analysis.
• Integrable with company MES/MRP systems.
• Remote access for diagnostics and problems solving

Dies lubrication

The proper dies lubrication makes the difference for a successful hot forging process.

A correct lubrication does not mean a lot of lubrication, but it must be properly dosed, the most suitable lubricants must be chosen based on the metal to be forged and the required piece.

We propose:

• Automatic air-oil lubrication unit managed by the control panel.
• Up to 30 lubrication points.
• Automated lubrication arm synchronized with the forging cycle.

Dies changing system

To allow a quick unlocking, the die holder has been optimized, and the auxiliary arm becomes essential for bringing the dies out of the working area of ​​the press.

Dies pre-heating

This is an important phase of the hot forging productive process that foresees the use of modern induction technologies avoiding open flames or CO2 emissions.

In the fashion sector, therefore, hot forging presses and related devices are widely used.

It is always important to develop an accurate and successful forging project to maximize profits and reduce waste.
