METHOD FOR MANUFACTURING AN INTERDENTAL CLEANING TOOL AND THE INTERDENTAL CLEANING TOOL
To provide a method for manufacturing an interdental cleaning tool that can prevent deformation of a core base at molding of a cleaning flexible part using an elastomer material, thereby effectively preventing occurrence of molding failure of the cleaning flexible part.
The method in the present invention includes: a base part molding step of providing first metal molds 30 and 31 for molding base parts with a plurality of first molding spaces 32 aligned in parallel and including core base molding sections 32a and handle base molding sections 32b, providing the first metal molds 30 and 31 with connection part molding sections 35 to communicate with the adjacent handle base molding sections 32b, and supplying a synthetic resin material with a fiber material at a time to the plurality of first molding spaces 32 from gates 34 to form a plurality of base parts at a time; and a flexible part molding step of setting the core bases of the base parts into second metal molds, holding the core bases at two or more longitudinal portions by a plurality of pairs of hold pins in the second metal molds, each pair including two pins, and charging an elastomer material into the cleaning flexible part molding spaces.
Method for making asphalt compositions and substrates coated therewith having improved properties
A method for forming a coating composition for coating a substrate comprising: blending an asphalt material; a polymer that is not a polyol; and a polyol wherein the polyol has a molecular weight of about 1000 to about 5000. Also, included are coated articles that comprise a substrate coated with a layer of the coating composition.
THERMOPLASTIC RESIN COMPOSITE AND PREPARATION METHOD OF THERMOPLASTIC RESIN COMPOSITE
A method of preparing a thermoplastic resin composite includes laminating a matrix resin layer and a reinforcing resin layer to prepare a resin laminate, and heat-bonding the resin laminate, and prior to the step of heat-bonding the resin laminate, fixing one or more selected from the group consisting of the reinforcing resin layer and the resin laminate using a stitch resin having a draw ratio of less than 10:1 and a melting point of 150 C. or lower.
Additive manufacturing powder and method of manufacturing the same
Additive manufacturing powder contains a core-shell type particle containing a core particle comprising a first binder resin and a filler and a shell present on the surface of the core particle. The shell contains a second binder resin. The powder has a particle size distribution Dv/Dn of 1.5 or less and an average circularity of from 0.800 to 0.980, the average circularity being represented by the following relation:
Average circularity=(a perimeter of a circle having the same area as a projected image of a particle)/(the perimeter of the projected image of the particle)100.
METHOD AND APPARATUS FOR CONTINUOUSLY PRODUCING A SEMI-FINISHED PRODUCT FOR THE PRODUCTION OF SELF-SEALING TYRES
An apparatus, and relative method, for producing a semi-finished product with a strip of sealing compound for building tyres, having at least one unsaturated styrene thermoplastic elastomer, one bonding resin and one cross-linking agent are described.
MICROFLUIDIC PUMP AND VALVE STRUCTURES AND FABRICATION METHODS
Plastic microfluidic structures having a substantially rigid diaphragm that actuates between a relaxed state wherein the diaphragm sits against the surface of a substrate and an actuated state wherein the diaphragm is moved away from the substrate. As will be seen from the following description, the microfluidic structures formed with this diaphragm provide easy to manufacture and robust systems, as well readily made components such as valves and pumps.
Spinal injection trainer and methods therefor
A model for anatomical training includes a visibly clear thermoplastic elastomer matrix formed with at least one contoured surface, the contoured surface simulating at least a portion of a human body. The visibly clear thermoplastic elastomer matrix provides visible needle tracks upon needle penetration that may be fused closed upon heating the thermoplastic elastomer matrix such that the needle tracks are no longer visible. The model includes a skeletal structure embedded within the thermoplastic elastomer matrix at the same location, relative to the contoured surface, as the corresponding skeletal structure is located in a human body, the skeletal structure producing a fluoroscopic image representative of human bone corresponding to the skeletal structure.
