METHODE DE FABRICATION DE SIMILIBRIQUES A PARTIR DE PLASTIQUE ET AUTRES MATERIAUX A MOULER, AVEC OU SANS MATERIAU DE REMPLISSAGE

METHOD OF MANUFACTURING SIMULATED BRICK PRODUCTS FROM PLASTIC AND OTHER MOULDABLE MATERIALS WITH OR WITHOUT FILLER

Abrégé anglais

ABSTRACT OF THE DISCLOSURE
This method of manufacturing simulated brick products from plastics and
other mouldable materials utilizes a high intensity mixing machine to tranform the
material into a malleable form from which brick-like articles can be moulded. The
materials can be formulated to give properties and appearances as required for
specific uses.The products can be manufactured in one piece utilizing a single
material or can be made as a shell whereby another material is used as a filler.In this
case the filler is also used as a die in the moulding process and is configured to
allow good flow and positive adherence to the outer shell.

Revendications

THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1) A process to manufacture simulated brick products from plastic and other
mouldable materials with or without filler using a high intensity mixer and
compression moulding techniques.
2) The use of a pre-manufactured filler as the female die portion of a mould
to manufacture filled brick type products.
3) The utilization of a locking groove to lock a shell to a filler in simulated
brick and other products.

Description

THE MANUFACTURE OE SIMULATED BRICK PRODUCTS FROM
PLASTIC AND OTHER MOULDABLE MAT~
The present invention relates to a method of manufacturing brick like
products from plastic and other materials. This process utilizes a high intensity
mixing machine which transforms materials into a malleable state. The material is
then moulded into products which have the appearance of brick and properties
dependent upon the ingredients used. This process allows for the use of a wide
variety of mixed materials, a subsequent unlimited list of properties and very low
manufacturing costs. The products that are made with fillers can utilize less
exp~nsive, more readily available, or otherwise more appropriate materials for their
interiors. These materials would also be processed in a high intensity mixer.
While the products are formed using conventional compression moulding
techniques, the process to make the products with fillers utilizes two new features.
The first is to use the filler as the female die part of the formi~g mould and the other
is to configure the filler as to lock it to the shell.( see Fig. 1 )
As an example, a filler for a brick shaped product would be made slightly smaller
then the finished product. This filler would be allowed to harden and would then be
used as a die to form the finished product. The filler would adhere to the shell by the
intrinsic properties of the heated materials and by the locking groove in the filler. ~ -
