General indications

 

Types of products

Due to the nature of our website (online sales), Hiro suggests producing small furnishings and home design objects, such as: coffee tables, tables, stools, organization containers, trays, wall mirrors, table mirrors, wall clothes hangers, standing clothes hangers, shelves, candle holders. Other objects may be assessed by the company, but Hiro does not guarantee that they will be processed.

 

Materials

It is necessary to use metal (carbon steel, stainless steel, aluminium) in the products you produce with Hiro. That's because we have a long experience in manufacturing metals and we want to produce your projects directly. In this way, we can keep lower prices and give you more guarantees of control on the manufacturing process. Moreover, metal is suitable to many different manufacturing processes and is cheaper than many other materials. You can combine metal with wood, glass and mirrors.

If you want to include other metals such as brass or copper in your project, please contact us to know whether we can accommodate your request. Likewise, if you need to use other materials besides wood and glass, please contact our technicians.

We are always looking for new materials and manufacturing processes, to give you the opportunity to create whatever you want.

 

Manufacturing processes

Not all manufacturing processes are available for the objects you produce with Hiro, due to our production in small and medium lots.

For example, fusion and moulding are two processes that are too expensive and problematic to be suitable to small productions. However, there are alternative possibilities that can create very similar effects: our technicians may advise you on how to revise your project for a simpler and cheaper manufacturing.

Find out all the types of manufacturing processes and their technical specifications below. If you don't find the kind of process you are looking for, or the size of your object does not allow it, please contact us to check for possible changes to the project. We will be glad to help you look for the most suitable solution for your needs.

Manufacturing processes

 

Welding

Welding is a process that allows the union of two joints by melting them directly or by means of adding more metal. The technologies we use, are:

  • MIG / MAG welding
  • TIG welding

Metals weldability
Please consider that not all metals have the same weldability. Steel, generally, is easier to weld than other materials. Hiro reserves the right to assess during the engineering phase, the feasibility of welding for metals other than steel.

Aesthetic quality
Please consider that joints may be “grinded” or “at sight”. When “grinded”, you won’t see the joint of the two parts, and the object will look like a single piece. When “at sight”, weld beads are visible.

Sizes and limitations
There are no particular limitations in the use of welding except, as we pointed out previously, the kind of material. In any case, an evaluation of the project is necessary in order to choose the most suitable type of welding (both for aesthetic purposes and mechanical stress). Our technicians will be able to advise you about the best choice of welding. If you’d like, you can specify on your project whether you prefer “grinded” or “in sight” welds.

How you can use it
Welding allows you to realize different kinds of “structures” by connecting two steel profiles. It is the most “classical” way to build different kinds of home design objects.

 

Bending

Bending is a mechanical process which distorts an object by applying force to it, with the result of getting flat semi-finished products. Bending is a cheap and versatile procedure. When possible, since it is more affordable, it is better to use bending than other processes like welding or mechanical fastening (screws, etc...).

Bending with a press brake
As there are no costs to produce a mould, it is advantageous to use this technique in case of limited productions.

Bending with a mould
This technique uses a mould which is installed on a press. It is usually used to produce a larger number of pieces, as it amortizes the initial cost of the mould and allows an easier production of “series”. Hiro does not currently use this technique due to its high costs which cannot be amortized by the suitable economy of scale. To obtain some specific results (e.g. curves, bulges etc...) you can use metal turning (see below).

Sizes and limitations
We can perform “U” or “V” bends. Please remember that this kind of technique does not achieve “sharp edges”, and the bend radius needs to be taken into account. The minimum bend radius strictly depends on slabs' thickness, the piece's final size and some other factors that need to be evaluated for each project.

How you can use it
You can build many décor objects thanks to bending techniques: squared-off trays, object containers, candle holders, shelves, frames and any other object designed with a “plane curve”.

 

Punching

It is a cheaper procedure than laser cutting when there are many holes. Moreover, this kind of procedure allows to perform small deformations, such as embosses, with ornamental aim (patterns, etc.).

Sizes and limitations
Sizes allowed for this kind of procedure vary depending on the type of material and slabs' thickness.

How you can use it
You can create decorative “patterns”, such as an embossed metal sheet. You can also create holed surfaces with a “mesh” effect.

 

Metal turning

Procedure similar to moulding but with much lower costs for machinery. Metal turning (or spinning) allows the deformation of metal slabs or sheets, by forcing a metal disk against the wall of a mould to obtain an object with axial symmetry.
Essentially, any ductile metal can be shaped by this process: iron, aluminium, copper, brass, different kinds of steel up to stainless and special steel. Diameter and depth of the parts are limited only by the available machinery's dimensions.

Sizes and limitations
For all materials, usable thicknesses go from a minimum of 0,8 mm to a maximum of 3,0 mm. We can also shape micro-perforated iron and stainless steel sheets.

How you can use it
You can create a variety of different objects with this technique: lamps, vases, cups, etc...

 

Metal wire

With metal wire (or “rod”) processing, we mean a series of procedures performed on a circular rod. Specifically, we refer to bending procedures which allow to give different shapes to the “metal wire”. It is performed automatically by CNC (Computer Numerical Control) machines. We process special rods and profiles (flat, oval).

Sizes and limitations
We can process rods with up to 12 mm diameter. Steel wire may be cut from a minimum 5 mm up to 3 m.

How you can use it
You can use this process to create hooks and supports, but also structures for chairs, stools, handles, etc...

 

Calendering

Calendering allows modelling metal sheets or profiles, pushing them through parallel rolls arranged in a way that makes the sheet follow a circular trajectory. Ideal for circular or conical (open or close) profiles.

Sizes and limitations
Sizes allowed in this procedure depend on the sheet's thickness and on the curvature radius. Consider a minimum 120mm diameter.

How you can use it
Ideal for circular or conical (open or close) profiles. For example: vases, flower pots, lamps.

 

Laser cutting of metal sheet

Cutting of metal sheet (steel, stainless steel and aluminium) performed by laser technique. It allows to define a perimeter and to create a pattern or decorative drawings. It consists of a heating process through which the laser beam melts the material that has to be cut. Its main characteristic is a precise edge, with a perfectly flat and clean cut.
This technology can be used on all metal materials.

Sizes and limitations
Carbon steel can be cut with a thickness up to 20 mm, while stainless steel maximum thickness is 15 mm.
Aluminium alloys however, can be easily cut only with a thickness up to 10 mm per sheet.

How you can use it
Laser cutting is essential for many parts of your project. It substitutes manual cutting when more precision is needed. In the case of small lots and simple perimeters however, manual cuts and finishes might be more convenient. Laser cutting allows you to get peculiar outlines and to engrave drawings on plane sheets.

 

Laser cutting of tubes

It is the same “laser” technology as described above. In this case, tubes and different kinds of profiles are cut: round, elliptical, squared, rectangular, flat-oval.
We can efficiently process aluminium, stainless steel, iron. Besides performing holes, loops, various degree cuts, this technique allows to create outlines which would be difficult to get without using moulds.

Sizes and limitations
Round section: diameter min. 12 mm / max. 120 mm.
Rectangular section: diagonal 140 mm with maximum variance between sides of 100 mm.

How you can use it
You can create profiles to build clothes hangers, chairs, structures for small bookshelves.

 

Tube bending

Tube bending with CNC technology. We can perform regular or irregular curves.

Sizes and limitations
Limitations may vary according to thickness and radius of curvature. Contact our technicians to verify.

How you can use it
Chairs and seats in general, curved profiles.

 

CNC turning

Turning is a procedure of material removal. It can be distinguished in:

  • External turning: the external part of the piece is processed
  • Internal: processing of the internal part of a hollow piece

The piece can also be placed to obtain turning on eccentric parts.

Sizes and limitations
This kind of procedure does not present any specific problems. Limitations are based on the maximum sizes that can be processed by CNC machines.

How you can use it
You can create vases, containers, object holders, candle holders and other décor elements.

 

Finishes

Powder coating, spray painting of RAL colour chart
RAL is a term used to define a colour matching system mostly used mainly for varnishes and coatings.

Upon request, we may obtain special paints and finishes.
