The invention discloses a foaming, welding, forming and manufacturing process of a complex shoe body. A target formed complex shoe body has a plurality of complex raised grains or holes or color blocks, and forming process materials of the target formed complex shoe body include a shoe material which contains an unexcited foamer, a cold pressing mold, a foaming and welding mold and a finished shoe forming cabinet; during production and manufacturing, the shoe material which contains the unexcited foamer is prepared into sheets or agglomerates and then is divided into parts and components of the shoe body through cold pressing by the cold pressing mold, the parts and the components of the shoe body are put in the foaming and welding mold and are heated by the finished shoe forming cabinet so as to foam, forming and weld the parts and the components, and the complex shoe body is formed by a plurality of simple spare parts. According to the foaming, welding, forming and manufacturing process, the structure of the mold can be greatly simplified, the labor intensity of operators is reduced, the production speed and the one-time rate of good products are increased, the defects of difficulty in manufacturing the mold of the complex shoe body, long forming and manufacturing cycle, high defect rate and the like are overcome, the maintenance and service are facilitated, the structure is reliable, the cost is low, and multiple purposes are achieved once.

A disclosed manufacturing method for fiber tubes comprises the following steps: (1) prefabricating bulk foam powder; (2) coating with a plastic interlayer; (3) reeling fiber cloth; (4) curing molding; and (5) taking out the finished product from a forming die. According to the manufacturing method, a foam powder is used for preparation of the bulk foam powder with a shape identical to the tube shape according to the shape of the tubes; then the plastic interlayer is covered, the fiber cloth is reeled, and curing molding is performed, thus a conventional mode that a fiber tube is filled with foam particles is replaced, so that the bulk foam powder is heated uniformly and expands, and thus an inner pressure is formed from the interior and the fiber cloth is expanded and clings to the inner wall of the die for molding, so that the manufacturing method helps to put an end to sand inclusion caused by the easily overflowed foam powder and molding defects comprising fake connection and the like caused by hollow foam powder, and effectively improve molding yield rate; and the manufacturing method is simple to operate and has substantially improved working efficiency.

The invention discloses an AMOLED display device and a manufacture method thereof. The AMOLED display device includes a TFT backboard provided with a plurality of pixel electrodes and a drive transistor; a face board part arranged facing the TFT backboard and provided with a display face and a packaging face arranged opposite to the display face; a pixel definition layer disposed between the TFT backboard and the face board part and including a first pixel definition layer formed on the TFT backboard and a second pixel definition layer formed on the packaging face of the face board part, wherein the second pixel definition layer is connected with the first pixel definition layer fixedly. The AMOLED display device is comparatively simple in manufacture, high in yield rate and low in material cost.

The invention relates to sheet bending and forming mould and method. The forming mould comprises a die, a terrace die and an eccentric swage arranged between the die and the terrace die; the shape of the forming face of the terrace die is the shape of a bent finished workpiece; the die comprises a first sub die, a second sub die and a third sub die; the three sub dies are respectively matched with the eccentric swage and the terrace die to carry out three-time mould pressing on a sheet; the first sub die has a die orifice and comprises a first wrap angle part and a transition section transiting to the bottom of the first sub die from the first wrap angle part; the first wrap angle part limits the die orifice and corresponds to the convex corner edge of the finished workpiece in shape; thesecond sub die has an inner side wall corresponding to the side of the finished workpiece; and the third sub die comprises a second wrap angle part corresponding to the convex corner edge of the finished workpiece in shape and an inner side wall extending along the shape of the side of the finished workpiece form the second wrap angle part. The sheet bending and forming mould and the forming method can reduce wrinkling during sheet bending and improve the sheet forming yield.

The invention discloses a non-phosphorous low-carbon aluminum-magnesium non-fired brick for stainless steel ladles and a manufacturing method thereof, comprising high-bauxite of different particle levels, fused magnesia, corundum powder, spinel powder, alumina micropowder, silicon carbide Additives, wetting agents and phenolic resin binders, the mass percentage of each component is: 5-3mm high-bauxite 15-20%, 3-1mm high-bauxite 20-25%, ≤1mm high-bauxite 10-15%, 3-1mm fused magnesia 10-15%, ≤1mm fused magnesia 5-10%, corundum powder 10-15%, spinel powder 15-20%, ≤25μm alumina powder 2- 5%, silicon carbide additive 0.1-2%, wetting agent 0.1-2%, plus binder phenolic resin. Compared with the prior art, the outstanding advantage of the present invention is that it omits the firing process in the conventional method, saves energy, and does not contain phosphorus. Compression molding makes it have a higher density, avoids pollution to the stainless steel molten steel, and also has a higher service life.
