TWO COLOR PROCESS
The invention is a method of manufacturing a multi-color molded furniture item made by a multi-step molding process using heat zone control in the mold to apply different plastic charges to predefined portions of the mold. Controlling zones of the mold with heat by zone heating and thermal insulators separating mold zones for molding a part of different plastics differing in characteristics such as color, durability, surface finish and chemical resistance.
One-step solution casting method for preparing polyvinylidene fluoride-based pyroelectric polymer film
A one-step solution casting method for preparing a PVDF-based pyroelectric polymer film is provided, which belongs to the technical field of functional material preparation. The method comprises steps of: treating a substrate with a hydrophilic reagent to obtain a hydrophilically-modified substrate, and then casting the organic solution of polyvinylidene fluoride (PVDF) or its copolymer on the hydrophilically-modified substrate. After cured, the as-casted PVDF-based film shows pyroelectricity without undergoing any stretching or poling post-treatment, indicates that the dipoles of the one-step prepared film are aligned. The self-polarization of the prepared film is attributed to a hydrogen bond induced layer-by-layer electrostatic self-assembly growth mechanism. The method is simple, low cost, high efficient, high capability to produce thick and large-area film with smooth morphology and ease to be scalized.

Powder slush molding system
Disclosed is a powder slush molding system that molds a slush skin by melting and adhering a powder resin material to an inner surface of a mold that is heated. The powder slush molding system includes a heating device, a rocking device, a cooling device, a demolding device, and a transfer device configured to transfer the mold between these devices. The cooling device includes a cooling bath and a table configured to turn upside down vertically above the cooling bath. The mold fixedly placed on an upper surface of the table faces the cooling bath side when the table is turned upside down. The table is configured to allow the mold to be placed also on a back surface of the table. The back surface faces upward when the table is turned upside down.
