An injection molding that emits an anion and far infrared rays according to the present invention is obtained by mixing and injecting a powder of any one selected from the above-described various coral-based ceramics into a resin. Such injection moldings may be used as ornaments or ornaments by themselves, but may be completed as finished products through processing or polishing as necessary.

Here, the resin may be used a variety of things, for example, nylon (N ₆ , N ₆₆ , N ₁₁ ), polyacetal (POM), polybutylene terephthalate (PBT), reinforced polyethylene terephthalate (reinforced PET), Polyvinylene sulfide (PPS), polyether ether ketone (PEEK), wholly aromatic polymestel, thermoplastic fluorine resin (PEA, ETEE), polyarylate (PAr), polysulfone (PSu), polyethersulfone (PES) , Polyetherimide (PEI), polytetrafluoroethylene (PTFE), wholly aromatic polyester, polyimide (PI), polyaminobismaleimide (PABM), dry resin, crosslinked PI.

The finished ornaments or ornaments thus generate negative ions, far infrared rays, or at the same time negative ions and far infrared rays, causing beneficial pharmacological phenomena to the body.

That is, depending on the composition of the oxide-based ceramic powder used, only the anion may be emitted, only the far infrared may be emitted, or the anion and the far infrared may be emitted simultaneously.

Moreover, resin can be manufactured by mixing a coloring agent and a pigment in various ratios as an additive according to the use, productivity, and the characteristic of a product or a component.

The injection molding which emits anion and far infrared rays according to the present invention can use various injection methods according to its use. When injection molding by mixing oxide ceramic powder and resin, compression molding and transfer molding ( Transmoulding, Extrusion Molding, Blow Molding, Vacuum Molding, etc. may be divided into methods, and these manufacturing methods will be described in detail below.

(1) Compression Molding

-The appropriate amount of material needed to mold the product to be shaped is usually made into a tablet tablet.

-Preheat in a high frequency preheater (eg heat up to 90-120 ° C within 1 to 2 minutes for phenolic resin). The reason for preheating is to shorten the heating time in the mold to shorten the curing time, to remove moisture contained in the material by heating, to prevent defects and defects in the molding of the product, and to lower the molding pressure.

-Charge the material into the cavity of the mold which is preheated by continuous operation.

-Then, the mold is melted and melted and flows to the front surface of the cavity by fastening the mold at the first low pressure (about 50kgf / cm ² ) and heating it. At this time, a process of discharging the gas in the material may be included.

-If the mold is continuously heated while tightening to the secondary high pressure (about 150 ~ 300kgf / cm ² ) (molding temperature about 140 ~ 180 ℃), it will be hardened by the characteristics of the material. Open the mold in and take out the product. This whole process becomes 1Cycle.

(2) Transfer Molding

-Prepare a tablet-shaped material made by weighing one serving.

-Preheat and inject into Transfer Pot, which is a material receiving chamber, and heat and soften it.

-Fill with cavity through sprue and runner by heating with plunger.

-It is a molding method that produces a desired product by curing a molding material by heating a mold.

(3) Extrusion Molding

-Put the powder or pellet shaped material into the hopper.

-Plasticize by heating and mixing in the heating cylinder,

By extrusion pressure in the forward direction by the rotation of the screw, the molten molding material is extruded through a hole of a die having a shape to be produced.

-It is a method of obtaining a molded product of desired shape by cooling and solidifying.

(4) Blow Molding

-Using the principle of extrusion molding, a part of a tubular molded product which is extruded into a tubular shape (this is called a Parison) is sandwiched between both ends of the mold in which the product shape is processed.

-After closing the mold (the bottom part of the parison is cut and fused)

-Blow the compressed air through the air inlet inside this parison to expand the material and fix it to the mold inner surface.

-How to cool the mold to open the mold and take out the product

(5) Vacuum forming method

-Clamp the plastic sheet on the upper part of the mold and plasticize it by heating the plastic sheet with a heater, etc.

-If the internal air hole is pulled out through the drilled air hole in the lower part of the mold, the sheet is adsorbed and molded on the inner surface of the mold shape.

-After molding, blow air through the air hole and take out the product.

(6) Injection Molding Manufacturing Method

-The material is first dried to remove moisture sucked into the material, and then filled into a hopper, a material receiving chamber attached to the injection molding machine, and the raw material is rotated by the rotation of the injection screw in the cylinder of the injection machine. From what is in the part, it enters the cylinder and plasticizes. The cylinder allows the outside to be wound with a heater and the material to be introduced is heated and melted to make it fluid.

-With the upper mold of the mold fastened to the nozzle part (fixed side fastening part) of the injection molding machine and the lower mold of the mold fastened to the ejector part (movable side fastening part), the movable side of the injection machine moves in the fixed side direction, Lower and upper pictographs are closed. At this time, the mold should be closed with a strong clamping force so that the mold does not open at a strong injection pressure.

-After contacting the nozzle of the injection machine with the sprue which is the starting point of the flow part of the upper part of the mold, advance the injection screw with the hydraulic cylinder and evenly distribute the resin in the heating cylinder in the cavity through the flow part of the mold. Injection at high pressure to fill.

The plastic filled in the mold is shrunk by the process of cooling the mold to solidify the product. If the plastic shrinks in the cavity, the quality (dimension accuracy and appearance) of the product will be degraded, so that the injection pressure is maintained without being solidified to prevent this. This is called packing.

This allows the material to shrink and further replenish the raw material in areas where there is space in the cavity to prevent quality degradation. In addition, since the injection was performed at a high pressure, the raw material may flow backwards and flow out if it is not provided at the back with a strong pressure. The process required for both is a packing process, which lasts until the gate is hardened so that raw materials cannot flow out or cannot be replenished.

While the mold is cooled and the product is solidified, the injection screw in the injection cylinder is rotated by the hydraulic motor, receiving material from the hopper and sending it through the screw's acid to the nozzle. At this time, the material is compressed and rubbed with the cylinder wall surface to generate heat, and is heated by the band heater, so that the material is melted and moved to the front nozzle. The raw material is continuously filled in the front part of the nozzle and the screw is retracted until the limit switch installed for weighing is pressed.

-After the plasticizer of the injection molding machine is finished, the nozzle of the injection molding machine retreats backward and the mold is opened.

-After the mold is opened, the ejector rod installed on the moving part of the injection molding machine moves forward by the operation of the hydraulic cylinder, and the ejector pin pushes the product by pushing the ejector plate forward by pushing the ejector rod installed on the mold forward. Let's do it.

-The mold is closed again. Repeating this process is the principle of the molding process, and 1Cycle is performed for each process from 1 to 8.

The ceramic powder is mixed with the resin by injection molding such as the above-mentioned compression molding, transfer molding, extrusion molding, blow molding and vacuum molding.
