A MOULD SET FOR FABRICATION OF AN EPS PALLET AND USE THEREOF
The present invention provides for a mould set for fabrication of an EPS pallet, a process for making the mould set for fabrication of the EPS pallet, and a process for fabricating the EPS pallet using the mould set. The mould set includes a modular platform mould and a leg mould configured to fabricate a platform section and plurality of leg support sections of the EPS pallet, respectively. The modular platform mould includes a modularity unit which enables alternation of dimension of hollow space which is configured to receive feed of polystyrene beads and thereby enabling moulding of the platform section of varying dimensions from a single mould. The one or more leg support sections are affixed to bottom side of the platform section at predefined locations, based on weight bearing capacity and position of lifting, to form the EPS pallet. The easy customization into various sizes as per requirement using a single mould structure reduces requirement of hoarding various moulds for different dimensions of EPS pallet, thereby significantly reducing the cost of moulding operations.
METHOD FOR FUSING PARTICLE FOAMS BY MEANS OF POROUS SLEEVES
A process for producing a molded article involves providing a thin-walled, gas-permeable shell; filling the shell with a foamed pelletized material composed of a polymer; and welding the foamed pelletized material to obtain the molded article. Molded articles are obtainable or obtained by such a process, and can be used as a footwear sole, part of a footwear sole, a mattress, a seat cushion, an underlay, a grip, a protective film, a component in automobile interiors and exteriors, a gymnastics mat, a body protector, a trim element in automobile construction, a sound insulator, a vibration damper, a cushion, a bicycle saddle, a toy, a tire or part of a tire, a covering for a track and field surface, a covering for a sports hall or a pathway, a damping layer or a damping core in a sandwich element, or a packaging.
Method for producing resin molded article and shoe sole member
Provided is a method for producing a resin molded article including an introducing step of introducing a plurality of resin foam particles and a heat medium substance into a forming mold, and a molding step of, after the introducing step, heating the forming mold to a temperature at which the heat medium substance can be vaporized, thereby obtaining a resin molded article including the plurality of resin foam particles.
USE OF ELECTROMAGNETIC RADIATION IN THE PRODUCTION OF POPCORN-CONTAINING SHAPED PARTS
The present invention relates to two-dimensional and three-dimensional shaped parts and composite materials made of popcorn and synthetic and/or natural binding agents which are cured in automatic moulding machines or similar pressing installations by means of radio wave technology or microwaves. By means of these technologies, light-weight, two-dimensional and three-dimensional shaped parts and composite materials can be produced for packaging, as interior and exterior parts (for example in automobile and mobile-home construction), shock absorbers, space-dividing elements, furniture, consumer goods, for the building trade of for heat insulation.
Method for preparing foamed thermoplastic polyurethane elastomer product
The present invention relates to a method for preparing a foamed thermoplastic polyurethane elastomer product, comprising the steps of: 1) coating a binder: coating the binder on the surfaces of expandable thermoplastic polyurethane elastomer particles; 2) curing and molding: adding the product obtained from step 1) to a mold and then placing it in a vulcanizing machine for curing and molding; and 3) cooling and setting: cooling the mold after the molding in step 2) to obtain the product of the present invention. By means of pre-coating the binder on the surfaces of expanded thermoplastic polyurethane elastomer particles according to the present invention, the weight of the binder can be reduced, and the properties of the expanded thermoplastic polyurethane elastomer particles can be utilized to the maximum extent.
