Design&Engineering
We formulate our design proposals and display them instantly on the screen, which permits quick
design development in direct collaboration with our customers. Our designers and engineers have
complete mastery of rotational technology and are thus able to take full advantage of the flexibility
of rotational moulding. The design proposals can be used to generate dimensioned drawings for
modelling purposes or 3D files for direct CNC mould production. The Persico Engineering Department
makes use of latest versions of the major 3D CAD systems (Omnicad, Catia, Solid Works, UG, Pro-E).
• Frame design with Finite Element Methods (FEM)
The use of structural FEM:
1. Optimizes frame design by adopting the optimal cross-section and structure.
2. Allows reducing the number of closure points (if desired, in combination with the Spider closure
system).
3. Minimizes total weight.
4. Aides in choosing the best springs to ensure uniform closure force.
• Laser frame design and manufacture
Innovative frame design using 3D files enables us to collaborate with our customers in the design
stage, as well as during the frame laser cutting process. The frame is produced during the milling
stage or during aluminium shell casting. Executing these two processes in parallel allows us to reduce
dead time.

Casting Dept
Persico Rotomoulding Division designs and manufactures:
• Scale models, which are constructed utilizing the most advanced rapid prototyping systems and are
used to check the part right from the design stage.
• F oundry models, which can be constructed out of any material either by hand or on CNC
machines. Models can be used as a prototype for the customer or as the starting point for the
manufacture of cast aluminium moulds.
Milling Dept
Persico was the first Italian company to use milling machines of dimensions up to 25 x 7 x h 3.0 m, as well
as other in-house milling machines (dimensions: 17.5 x 6.5 x h 2.5 m and 8.0 x 4.5 x h 2.0 m).
Precision and speed: Persico’s milling machines – some of which are of the latest generation with
magnetic motion control – execute single-block models and various types of moulds in such a short
time and with such high quality and dimensional precision that the results cannot be matched by
manual construction.
Greatly reduced production time: Persico can count on the support of several out-of-house milling
machines of various dimensions, some with magnetic motion control, in processing all project models
and moulds.

Surface treatments and finishes
Persico offers a variety of surface treatments and finishes that extend the useful life of moulds and
enhance the look of the moulded plastic parts. Hardening treatments or Teflon coating can be used
on the flanges alone or on the whole mould. Aluminium mould surfaces can be polished to make the
moulded plastic parts shinier. Moreover, the aluminium moulds can be finished in such a way as to faithfully reproduce the look of existing materials, such as wood, rock, terracotta, skin, antiqued materials
and others.

- No model is constructed (a special foundry process allows for bypassing the modelling stage).
- Assembly and internal profile are not given any special treatment.
- Surface finishing is done completely by shot-peening or sandblasting.
- No frame is provided and the mould closure is achieved by clamps mounted directly on the mould
flanges.

• CNC Moulds
- Persico’s 5-axis CNC milling machines produce high-quality moulds in much less time.
- CNC milling means greatly reduced milling and delivery time
- Higher quality, tighter tolerances and improved aluminium properties for large moulds.
- Extremely precise flange assembly and internal surface profile.
- Better surface finish from aluminium block than cast aluminium.
- The greater the complexity, the greater the benefits of CNC-machined moulds compared to cast
moulds.

New technologies implemented on Leonardo - the fully automated rotational machinery
The rotomoulding market has huge potential, but today it is hampered by the limited offering of polyethylene alternatives.
Some materials already on the market have not yet found their best use in the rotomoulding sector,
because they can cause problems during the traditional moulding process, due to the lack of automation and process control.
Therefore Persico’s R&D team has focused on improvements concerning materials:
PA6: starting with caprolactam chips fed through a dosing unit, rotomoulding of components on a
New Leonardo electrical heating machine.
Transparent polycarbonate: rotomoulding on a New Leonardo electrical heating machine
using a vacuum technique and specially treated moulds.

Multylayer: Multi-layer complex moldings can easily be achieved using automated material
delivery. Accurate temperature control helps ensure that foam depth and inner layer thickness
are controlled. Mold and Air temperature profiles can be used to accurately time the addition of
each layer of material. Soft material can be ‘over-molded’ into specific areas on a part (as sealing
surfaces or handles, for example) by control of heat flow.
Rotational moulding is a simple process, composed of four basic phases:
1. A pre-weighed amount of powdered or liquid plastic is placed in one
half of a thin-walled, hollow aluminium mould, which is mounted on
the arm of a rotomoulding machine. The mould is then closed with
clamps or bolts.
2. The mould is then biaxially rotated on perpendicular axes and moved
into an oven where heat is applied. The aluminium mould becomes
hot and the powder/liquid tumbling inside rises in temperature. Hot
material sticks to the mould in successive layers to form the part.
3. W hen the material has melted and has been consolidated, the
mould is moved to a cooling station, where forced air, water mist or
a combination of both is used to bring the part temperature down to
a point below the crystallization or solidification point of the material.
The biaxial rotation continues to prevent the material from sagging.
4. Once the part is cool, the mould is moved to an unloading station,
where the part is removed. The mould is then ready to begin the process again.
