Claims. 1
This invention relates to a proces for manufacturing a batch of molded material which gives a metallic appearance as of brass, bronze, silver, chrome or gold. The invention also applies to plastic molding material processed so that any ob; ject molded of the material gives th appearance of being made of one of said metals.
The plastic compound used for this process may be identified by its urea resin base or cellulose acetate base. Materials of the urea resin base,
in place of the bronze flake in such as formaldehyde urea resin, is preferable in the natural shade and may include an of the varied fillers used in moldin compounds, prepared with this base.
The basic molding substance used is ground to a fineness of sand particles, which has a fineness suitable for introduction into a stamping machine. The stamping machine used consists preferably of a revolving-cam, for lifting and dropping a shaft to which are attached steel shoes that strike against the bottom of a kettle of steel. This process produces a flaked or floured material.
The thus obtained basic molding material is introduced in this stampin machine together with a small quantity of binding grease such as lard, for instance, to give to said material body a flour like or flaky consistency. The time required for reducing the molding material from a grain to a floured or flaked consistency depends upon the type of material used.
The stamping process, no matter what basic material is used, is continued until the same is reduced to a floured or flaked consistency of about 200 mesh,
In order to produce a batch of molding material, which simulates brass, bronze, gold, silver or chrome, it is now necessary to add to this flaked basic material a quantity of bronze in flakes of about 200 mesh in the case of alloys of brass, bronze and gold or aluminum ink flake, and also in case or simulation of silver or chrome. The bronze flake ink or the aluminum flake is treated in the same type of stamping machine and is the result of the reduction of hammered, leafed metals of bronze or aluminum.
It is to be understood that a line bronze flake or aluminum flake will flow better and will permeate the molding material when the curing in the molding process takes place.
To the floured molding substance a bronze flaked ink or aluminum flake of 200 mesh with a stearine consistency is added in the proportions of about one ounce of bronz flake or aluminum flake to two ounces of flour molding substance. The bronze or aluminum ink is lighter in shade than the final brass or gold'tone required, because the molding process will oxidize the bronze or aluminum flake and thereby regulate the bronze or gold shade desired. The same process also applies to aluminum ortin flake when-used order to obtain a silver or chrome finish.
After the flour molding substance and the flakes have been mixed, the complete mixture is then-polished in a brush mill until the metal flakes are adhering to the flour substance and thereby adding lustre when brushed on the metal flakes. r
The basi substance consisting of urea resin, such as formaldehyde urea resin, or cellulose acetate is first prepared so that it can be ground to a finish to make it suitable for introduction into a specially constructed stamping mill to be mashed or crushed. In this mill the substance is reduced to a flour-like or flake-like consistency of about 200 mesh. Thereupon a binding grease such as lard is added to give the material body.
T.he metal flakes, whether bronze, aluminum or other metal after completion of the stamping process, are placed in a'polishing mill and polished with stearic acid, a tablespoonful of which is added to approximately 15 pounds of metal flake. The polishing process, as stated, is accomplished by a series of brushes, operating on a central shaft, rubbing against the corrugated surface of the walls of the cylindrical polishing mill. This process is continued for 12 or 24 hours depending upon the brilliancy desired on the flake of metal.
When the flaked part of the molding material has been prepared and the ronze flake or aluminum flake have been prepared in like manner, the two ingredients, the flaked molding material and the bronze flake or the flaked molding material and the aluminum flake, are mixed in quantities of 2 ounces of flaked molding material to 1 ounce of bronze flake or aluminum flake.
The cylindrical polishing mill polishes by rubbing the bronze flake or enclosed material against the inside corrugated surface of the mill with a' series of brushes. The flakes of the plastic material and the metal flour or flake are brushed until they adhere to each other.
It is of great importance that the mixed materials during the polishing operation do not become overheated since they tend to stick in the mill. It is, therefore, preferable not to continue this operation over 30 minutes, because this time is suflicient for brushing the flaked or floured substanc particles and the metal particles to- 3 gather. This process will add an additional lustre to the mixture. The combined material is now suitable for molding.
When quantities of this material are introduced in the proper weights into the steel molds, the cured product has the appearance of brass where bronze flake is used or of silver or chrome where aluminum flake is used. This material can be used industrially for the fabrication of plastic hardware, pipe fittings, or in whatever industrial field a substitute plastic product is desired.
This molding material is then ready to be put into steel molds and molded into objects which give a striking resemblance to brass, bronze or gold. Or in the case of the aluminum or tin flakes, a resemblance to silver or chrome.
The time for curing should be limited since over exposure causes added oxidation resulting in a dark appearance void of lustre.
It is to be understood that the invention as here described is not limited to the details herein but that the same may be varied widely without departing from the spirit of theinvention as defined by the subjoined claims.
