| titleOfInvention | Manufacturing process of needle tube |
| abstract | The invention discloses a manufacturing process of a needle tube, which comprises the following steps: first step, raw material preparation: the needle tube is prepared from the following raw materials in parts by weight: 50-100 parts of polypropylene, 30-60 parts of cyclohexane-1, 2-dicarboxylic acid diisononyl ester, 10-20 parts of ethylene and octene copolymer thermoplastic elastomer, 2-4 parts of polyformaldehyde, 2-8 parts of magnesium oxide, 1 part of silicon dioxide, 1 part of sodium oxide, 0.3-0.6 part of aluminum oxide and 2 parts of auxiliary agent; step two, mixing the raw materials: adding the raw materials in the first step into a batching box for stirring, wherein the rotating speed of a stirring motor is 2000r/min during stirring; step three, conveying raw materials: and the raw materials in the batching box are pumped out through a material pipe and conveyed to a storage bin of the injection molding machine. The invention forms a complete process by designing the procedures of raw material preparation, raw material mixing, raw material conveying, needle tube injection molding, cooling, demolding, cleaning, drying and packaging, and can prepare the needle tube with low-temperature-resistant strength and high-temperature-resistant toughness on the basis of material formula improvement. |
