Rotary molding systems and components thereof

A spider for a rotary molding process is provided. The spider includes an upper mold enclosure, a lower mold enclosure, and a clamping assembly. The lower mold enclosure is configured to selectively cooperate with the upper mold enclosure to facilitate retention of a mold housing therebetween. The clamping assembly comprises a collar, a plurality of brace members, and a clamping member. Each brace member is coupled with each of the collar and the upper mold enclosure. The clamping member is rotatably coupled with the lower mold enclosure and is rotatable about an axis in a clamping and unclamping direction. The axis extends through the collar. The collar is spaced from the upper mold enclosure along the axis. Rotation of the clamping member in the clamping direction facilitates translation of the collar towards the lower mold enclosure to facilitate urging of the upper mold enclosure and the lower mold enclosure together.

The present invention is a system for producing an object from a material that contains a hardenable base material using rotational moulding, wherein the system is comprised of a robotic arm and a die that can be attached to the robotic arm. The die contains a die cavity defined by a die wall, wherein the die is configured for receiving the material in the die cavity. The current invention also involves a method for production of an object of a material containing a hardenable base material using rotational moulding.

One-piece combined plastic urea and fuel tank with baffles, rotomoulded with a special mold heating system

The present invention relates to a plastic tank which provides storing of gasoline and urea liquid called adblue, used in automotive industry, particularly in vehicles which operate with gasoline and which reduces the damage of vehicles, which operate with gasoline, to the environment, in a single tank with two chambers, and relates to a special core heating system designed for production of this tank by using rotation technology.

SYSTEM FOR MANUFACTURING A SUPPORT STRUCTURE

A system cures and manufactures a partially-cured tire assembly. The system includes an annular hub member slid into a corresponding annular, radially inner surface, a plurality of elongate spacer members for maintaining corresponding uniform cavity dimensions by fastening the spacer members to the hub member with flap members thereby enclosing a radially outermost surface of each of the spacer members, a first annular curing platen for axially securing the hub member and spacer members relative to each other, a second annular curing platen for axially securing the hub member and spacer members relative to each other; and a plurality of elongate inserts.

Method for producing a container system and a liquid dispenser, as well as container system produced in this way and liquid dispenser produced in this way

A method for producing a containing system for a liquid dispenser having a dimensionally stable outer container and a collapsible inner container, in the form of a pouch, arranged within the outer container. The method includes starting from the outer container, at least one layer of a pouch material being applied to an inner wall of the outer container. For this purpose, the pouch material is applied in the form of a liquid or powder to the inner wall, where, after solidifying or fusing, it forms a ply of a wall, of the inner container. The ply detaches from the inner wall of the outer container when the inner container collapses.

Polyolefin compositions of a polyolefin, a chroman-based compound according to Formula (V):

##STR00001##

and a basic co-additive selected from alkali metal or alkaline metal salts of higher fatty acids are disclosed. Amounts of the chroman-based compound and the basic co-additive are selected to enhance processing stability of the polyolefin composition when subjected to extrusion, even in the absence of antistatic agents and organic phosphites and phosphonites. Masterbatch compositions of a first polyolefin, the chroman-based compound and the basic co-additive can be blended with a second polyolefin, identical to, or compatible with, the first polyolefin to form a stabilized polyolefin composition. Molded articles produced by molding the polyolefin compositions are also disclosed. R.sub.21, R.sub.22, R.sub.23, R.sub.24, R.sub.25, R.sub.26, and R.sub.27 are also described.

Method for producing shell and foam filler for a breast implant

A method for manufacturing a breast implant includes producing a silicone shell of the breast implant by rotating a mold containing a silicone material to evenly spread the silicone material over an inner surface of the mold. Subsequently, an elastic filler material including silicone foam is formed in the shell by (i) injecting into the mold a mixture comprising silicone gel and gas bubbles and (ii) rotating the mold to homogenize the mixture.
