摘要： The invention relates to a method of manufacturing a sandwich panel comprises the steps of:
a) providing a plate-shaped assembly of a first cover part and a second cover part and between these cover parts a core part of a thermoplastic material containing a physical blowing agent,
b) heating the assembly resulting from step a) under pressure between press tools in a press to a foaming temperature below the glass transition temperature of the thermoplastic material in the core part, thereby effecting adhesion of the foamed core part to the first and second cover parts
c) foaming the thermoplastic material in the core part under pressure and at the foaming temperature wherein the spacing between the press tools is increased;
d) a cooling step of cooling the foamed sandwich panel resulting from step c), while the sandwich panel is maintained under pressure between the press tools;
e) removing the thus cooled sandwich panel from the press; and
f) drying the sandwich panel thus obtained;
wherein the cooling step d) comprises a first substep d1) of cooling the foamed assembly from the foaming temperature to an intermediate temperature in the range of 70-100° C. at a first cooling rate and a second substep d2) of cooling the foamed assembly from the intermediate temperature to ambient temperature at a second cooling rate, the second cooling rate is less than the first cooling rate.

摘要： The invention relates to a microcarrier, comprising a continuous medium of a biocompatible polymer for culturing cells and having a three-dimensional scaffold architecture delineated peripherally by a continuous outer wall, in which spherical macropores are stacked to one another and interconnected by connecting pores. The continuous outer wall is formed with exposure pores at positions where it is in contact with the macropores, through which the interior of the microcarrier may be in fluid communication with the ambient culture medium. The microcarrier herein is produced by cast-molding and, therefore, has a continuous outer wall which provides additional mechanical strength while maintaining high porosity. The microcarrier thus produced is configured in the form of a basic geometrical body. The invention further relates to a cast-molding process for producing the microcarrier.

摘要： Disclosed is a microwave-transmitting mould structure, comprising a first template, a second template and a mould combining unit. The mould combining unit has a first snap fit, a second snap fit and an engagement member. The first snap fit is arranged on the first template; the second snap fit is arranged on the second template; and the engagement member is snap-fit engaged between the first snap fit and the second snap fit, so that when the first template and the second template are subjected to an outward pressure, corresponding faces thereof which the engagement member can pass through respectively abut against abutting faces of the first snap fit and of the second snap fit, and thus, the first template and the second template cannot be separated from each other due to an increased pressure inside the mould.

摘要： The present invention is a manufacturing method for obtaining a molded article having foam layer inside for providing a foaming agent, a device, a mold, a molding machine, a means for increasing the foaming ratio and a means for increasing coating appropriateness used for manufacturing resin having foaming properties. When the resin having compatibility (miscibility) with the resin to be blended is used as a carrier resin used for manufacturing a masterbatch of the foaming agent, the molded article having an excellent outer appearance can be obtained. When the sodium bicarbonate which is an inorganic foaming agent is used for the foaming agent, a sodium carbonate, which is a foam residue remaining in the molded article after the foaming agent is decomposed to generate the foaming gas, reduces the adherability of the coating film. Thus, when the acid cleaning is preliminarily performed to remove the sodium carbonate, the coating appropriateness is satisfied. When performing the GCP, the thickness of the skin layer located at the surface varies depending on the surface temperature of the mold. In general, the means using the heated steam is generally used for increasing the temperature of the mold. In the present invention, the means for heating the magnetic fluid (liquid) by high frequency induction heating is used. Thus, the temperature of the mold can be safely increased at low cost with heating efficiency. When a mold-back or a core-back is performed for obtaining the molded article having high foaming ratio, the resin is separated from the fixed side. The present invention provides the means for solving the above described problem of the separation by using the gas.

摘要： A forming mold for making polyvinyl chloride foamed wood-like slats includes an inlet, an outlet, and two main flow passages symmetrically arranged with respect to a central axis. The main flow passages each have an inlet section and an outlet section. The inlet section of each main flow passage is connected to the inlet. The extension direction of the inlet section of each main flow passage respectively defines with the central axis an included angle therebetween. The sum of the angles of the two first included angles ranges from 45 to 52 degrees. The longitudinal cross-sectional width of each main flow passage gradually decreases from the inlet toward the outlets. In this way, the forming mold of the present invention can effectively improve production efficiency and can increase the stability of the product manufacturing process.
