Definitions
- the invention relates to a method for obtaining a hollow plastic part having two walls. More specifically, the invention relates to the production of a structural self-supporting element, such as in particular a vehicle rear shelf, by heat-shaping a layer of air-permeable plastic material.
- An air-permeable material is difficult to use in accordance with the usual methods of thermoforming, because it is not very sensitive to blowing.
- the invention aims to overcome this problem, by proposing a simple, reliable and inexpensive method to carry out. To do this, the invention proposes to:
- a substantially airtight sealing film made of plastic material
- a substantially airtight sealing film made of plastic material
- first and second skins - using a mold comprising first and second movable elements relatively to each other between an open position and a closed position; in said closed position, said first and second elements each having a joint plane surface coming substantially into contact with that of the other element and reserving between them a molding cavity delimited on each of said first and second elements by an envelope surface,
- the first heated skin by placing the backing sheet essentially facing the envelope surface of the first element and said peripheral part facing the joint plane surface of the first element,
- the sealing films placed on each of the porous layers and pressed one against the other between the joint plane surfaces of the movable elements of the mold, along the peripheral parts of the skins, provide a satisfactory airtightness between the skins.
- the non-woven insulation sheet prevents the films from adhering in the event of simple contact when the mold is closed (before blowing).
- the pressure exerted by the elements of the mold allows migration of the material of the sealing films and of the plastic material of the porous layer through the nonwoven insulation sheet, the porous layer, the sheet wrong side and sheet.
- first nonwoven insulation sheet integrated into the first skin and coming substantially into contact with the sealing film of the first skin
- second nonwoven insulation sheet integrated into the second skin and coming substantially to the contact with the sealing film of the second skin
- the invention proposes that the nonwoven insulation sheet (s) be produced with polyester coated with polyethylene representing in proportion substantially 2/3 and 1/3 respectively of the surface weight included, which is between 10 and 100 grams per square meter.
- the invention proposes that to heat each skin, there is a heating element facing the porous layer and a heating element facing the sealing film.
- the place sheet comprises a carpet having an appearance surface and there is a heating element on the side opposite to its appearance surface.
- the carpet can be shaped more easily and with less risk of deterioration of its appearance surface.
- the invention further relates to a part having an external surface and comprising:
- a sealing film substantially airtight, made of plastic material
- a sealing film substantially airtight, made of plastic material
- each of the sealing films is placed close to the interior surface
- the hollow structure with porous walls of the part makes it possible to increase the acoustic and mechanical resistance characteristics, in particular the rigidity of the part, while reducing its weight.
- the presence of a sealing film prevents the introduction of dust or the like inside.
- each sealing film is at least ten times thinner than the corresponding porous layer.
- the weight of the sealing film is relatively negligible compared to the weight of the porous layer.
- the second skin successively comprises a nonwoven insulation sheet 18, a sealing film 16 of plastic material, a porous layer 14 based on plastic material, a nonwoven release sheet 12 and a carpet 11 having a surface. of appearance 11a and a bearing surface 11b opposite the surface of appearance 11a.
- the thickness of the components of each of the skins is not represented in proportion to reality.
- the first skin 10 is heated by a first heating means 21 comprising two plates 21a, 21b respectively coming into contact with the backing sheet 2, opposite the porous layer 4, and the nonwoven insulation sheet 18, in view of the sealing film 6.
- This first heating means brings the porous layer 4 and the sealing film 6 above the softening temperature of their plastic.
- the second skin 20, without the carpet 11 is heated by a second heating means 22 comprising two plates 22a, 22b respectively coming into contact with the nonwoven insulation sheet 18, facing the sealing film 16, and of the nonwoven release sheet 12, facing the porous layer 14.
- This second heating means brings the sealing film 16 and the porous layer 14 above the softening temperature of their plastic material .
- a heating mirror 23 is placed opposite the support surface 11b made of thermoplastic material of the carpet 11 to bring it above its softening temperature.
- the first 10 and the second 20 skins are then introduced into a blowing mold 25.
- This blowing mold 25 comprises a first element 26 and a second element 28 movable relative to the 'other between an open position in which they are spaced from each other and a closed position in which they come substantially into contact with each other.
- the first element 26 has a substantially planar joint surface 26a and an envelope surface 26b recessed with respect to the joint plane surface 26a.
- the second element 28 has a substantially planar joint surface 28a and an envelope surface 28b recessed with respect to the joint plane surface 28a.
- the envelope surfaces 28a, 28b define between them a cavity 30 into which a blowing cannula 32 opens.
- a peripheral part 10a of the first skin 10 comes into contact with the joint plane surface 26a via the backing sheet 2.
- a peripheral part 20a of the second skin 20 comes into contact with the plane surface joint 28a via the appearance surface 11a of the carpet 11, the bearing surface 11b of which is in contact with the sheet in place 12
- the nonwoven insulation sheets 8, 18 are then opposite one another and come substantially into contact with one another after closing the mold, without however adhering to one another.
- the marginal parts 10a, 20a of the first 10 and second 20 skins are then pinched between the joint plane surfaces 26a, 28a of the first 26 and second 28 elements of the mold 25.
- Air is then injected under pressure between the two skins 10, 20 via the cannula 32.
- the air pressure is then applied to the sealing films 6, 16, deforms the skins 10, 20, generates a recess 34 between the nonwoven insulation sheets 8, 18 defining the interior surface 36 and applies the reverse surface 2 and the carpet 11, apart from their peripheral part 10a, 20a, against the envelope surfaces 26b, 28b.
- the pressure exerted by the joint plane surface 26a, 26b of the first 26 and second 28 elements of the mold 25 on the peripheral part 10a, 20a of the first 10 and second 20 skins causes a migration of the plastic material of the porous layers 4, 14 and sealing films 6, 16 through the nonwoven insulation sheets 8, 18 in said peripheral portions 10a, 20a.
- the skins After cooling and demolding, the skins form rigid walls welded to each other by their peripheral part 10a, 20a, having between them the recess 34 and defining a finished part 1 having an outer surface 38.
- the outer surface 38 belongs to the back sheet 2 and to the aspect surface 11a of the carpet.
- the reverse sheet 2 is therefore visible on the finished part. It is advantageously made of felt or needled polyester fibers.
- the porous layers 4, 14 are advantageously made essentially of thermoplastic material and can in particular be obtained by needling glass fibers and recycled polypropylene in substantially equal proportions. They each advantageously have a thickness of between 2 and 5 millimeters.
- the sealing films 6, 16 are made of thermoplastic material compatible with the plastic material of the porous layer, advantageously of polypropylene. They preferably each have a thickness of between 100 ⁇ m and 250 ⁇ m.
- the nonwoven insulation sheets 8, 18, as well as the release nonwoven sheet 12 are advantageously made of polyester fibers (PES) coated with a polyethylene (PE) binder representing approximately 1/3 of the weight of leaf. They are substantially impermeable to air and their surface mass is advantageously between 10 and 100 grams per square meter, preferably substantially equal to 26 grams per square meter.
- PET polyester fibers
- PE polyethylene
- Such a product is sold under the brand Dexter and the reference Ipetex Thermoline 17280 PT 172. If the nonwoven insulation sheets 8, 18 are too dense, the welding between the two walls 10, 20 is not satisfactory. Conversely, if they are not dense enough, the sealing films 6, 16 cost each other elsewhere than in the peripheral part.
