When it is in the shape of a fat, it has a shape that is burnt out. The mixture is formed by dephases, short, and sticky. The radiation is high, and the heat does not lend the shrinking fat machine, which should be added and the addition of each, the radiation powder has the most important U, but the medium is large. The material powder is false and uses ___ viscosity. Therefore, the shape of the method is golden, and it will make the temperature of 彳, burn and deform to synthesize the final gold and its fat, so the lj material has low fat deficiency and fat formation, and it is more powdery than the mixed powder. To the "Η-合 the degree of fat removal and release of the shot is a system, the property is to use wh to heat the multi-temperature de-emission time to produce raw materials, the gold method of gold and plastic products to produce U amount plus sulfonate in the formation of the cause The shape is to make the hot shot ^ 纟 一 子 If you leave the cause.

Effect When the heating machine is used, the borrowing machine is used to wait for it to burn, add it. Borrowed shots) The objects have a complex shape. Θ ili: Wax is useful for this reason. The tangible seeds are used for t, 31, and i, which can be used to produce the knots. (The fakes are used to shoot the knots. (JMI brown makes the low things great, the ones who burn the fakes.) The make, the addition to make the roasted Msgr West, the rate The gelatin that enters into the solution can be obtained from the destination. Add it to # -r bar and the fat is viscous and internally divided into traps and hair extensions (this method is to make the fat group in the method). Because of the lack of stickiness of the heating unit ^, the shape of the subsequent use of acetic acid is made of inorganic knots (please read the precautions on the back before filling this page) This paper size applies to Chinese national standards (CNS) A4 specification (210X 297 mm) 513477 A7 B7 V.

The degree of Xue Wenjia's gathering is to use P ο make ο the agent bonding machine is useful to make the shape. The use of allylic polymerization can make the residual additions incomplete and cause cracks and burns. Sometimes there are knots with fat burning to stop the tree, and this is good. The shape of the pliable material can be synthesized with a low melting point, but it can also have the same poly 3 poly 1 ester.

Description of the invention (4) When the organic compound is added in an amount of less than 40 v ο 1%, the fluidity during molding is not good, and the molded product may crack or chip. In addition, if the added amount is more than 80 v ο 1%, the molded product may be jammed during molding, and the strength of the molded product may be reduced. Finally, by adding a thermoplastic resin whose Vicat softening point is below the Vicat softening point of the above (b) polypropylene as the (d) component, it can impart flexibility to the molded product and prevent fusion during molding. Defects such as bubbles. If the addition amount of the (d) thermoplastic resin is less than 5 v ο 1%, the viscosity of the molded product is high, and defects such as welding and air bubbles may occur during molding. If (d) the amount of the thermoplastic resin is 30 vo 1% or more, the molded product will become soft, and the deformation under 600 ¾ will increase during sintering. As the (d) thermoplastic resin, one or more resins selected from the group consisting of polyethylene, amorphous polyolefins, ethylene vinyl acetate copolymers, acrylic resins, polyethylene butyral resins, and methacrylic acid oxypropylene resins can be used. When the total of the components (a), (b), U) and (d) of the organic adhesive of the present invention is less than 30 v ο 1% by volume ratio with respect to the metal powder, the formed product is liable to become brittle. On the other hand, if the total of U), (b), (c), and (d) components is more than 60 vol% in volume ratio, the formed article is easily deformed in the range of 60010 or less during sintering. The injection molding composition of the present invention is formed by mixing (a), (b), (c), (d) the metal powder in a metal powder using a bath type or a continuous kneading machine.

Description of the invention (cross) ~ 6001C By adding a pressure of 0.1 ~ 500torr, the added (c) organic compound oozes out of the surface of the formed article and vaporizes. When the pressure is less than 0.1 torr, gasification occurs before the organic compound (c) oozes out of the molded product, and the molded product is cracked and expanded. If the pressure is greater than 5000 t rr, (c) the organic compound is not easy to ooze, and (c) the organic compound is not sufficiently removed from the formed product, so U) paraformaldehyde, (b) polypropylene, and (d) ) When the thermoplastic resin is thermally decomposed, the molded product is cracked and swelled. Examples of the metal powder used in the present invention include powders of stainless steel, iron bars, titanium, copper, and nickel. The average particle diameter of the metal powder used in the present invention is preferably 1 to 30 / im. When the particle size of the powder is less than lam, since a large amount of the binder is required during molding, defects such as deformation, cracking, and swelling are likely to occur during degreasing. On the other hand, if the average particle diameter of the powder is 30 / i or more, the powder is easily separated from the adherend during molding, and the density after sintering is low, and the strength of the obtained sintered product is also reduced. Printed by the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling this page). The above composition of the present invention is injection molded, and the resulting molding is directly placed in a sintering furnace at a processing temperature of 50 ~ 6001C is heated at a heating rate of 5 to 15010 / hr and a pressure of 0.1 to 500torr, and then heated at a heating rate of 50 to 40 0 ° C / hr, and sintered at 900 to 1500 ° C. A sintered body with no defects such as deformation, swelling and cracking, and very little residue from the adhesive is produced in a short time. At this time, when the sintering temperature was 9001C or lower, the sintered body was not sufficiently dense. On the other hand, if the maximum temperature is higher than 15 °, the molded product will melt, so you must pay attention to it.

In Comparative Example 4, deformation and swelling occurred during the degreasing process. This & because the added ratio of the binder is 7 2 v ο 1% pseudo-too much, the entire composition shows a substantial organic adhesive phase, and the whole shows plastic deformation. In Comparative Example 5, deformation occurred during the degreasing process. At this time, even if Li Zhan's -15-Zhang scale is applicable to Chinese National Standard (€ can) 8 4 specifications (210 '乂 297 mm), printed by the Staff Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 513477 Α7 Β7 ) The added ratio of the splice is 6 Ο ν ο 1%, which is more pseudo. The ratio of pseudo to the total amount of the adhesive to make the molded product stronger is 3 ν ο 1% is an abnormally small amount. In Comparative Example 6 above, bubbles and cracks were formed in the molded article during injection molding. For this reason, the polypropylene that imparts toughness (turn strength) to the molded product is 5%, so the wax may ooze out during molding. In Comparative Example 7, the metal powder could not be dispersed in the added organic compound. This is because the addition ratio of organic adhesive is 2 5 ν ο 1% is very small. These results indicate that the above-mentioned addition ratio of the organic binder to the metal powder and the range of composition and composition are proper. [Effects of the Invention] As described above, the composition for injection molding of the metal powder of the present invention is different from the conventional one, and hardly deforms after degreasing, and can be produced in a short period of time without cracking, swelling, etc. As a result, a sintered body having excellent dimensional accuracy can be obtained in a short time.
