An injection molding process using polylactic acid resin

At present, the main technical problems of polylactic acid resin injection molding are low heat resistance, poor fluidity, low gas resistance and lack of transparency. At present, various methods are being researched and developed to solve these problems. In addition, for example, injection molding of thin-walled products is made possible by the use of valve gates in order to overcome the disadvantage of poor fluidity.

Polylactic acid resin (PLA) is a plant derived resin with 100% plant starch and sugar as raw materials. It is an environmentally friendly synthetic resin that does not use any petroleum-based raw materials. In addition, the resin can be completely biodegraded into water and carbon dioxide by natural bacterial enzymes in the soil after waste. In other words, polylactic acid resin can be recycled only by changing the form of carbon semi-permanently, and can be used as an ideal carbon neutral and environmentally friendly material.

Polylactic acid resin has not been able to catch on in society at a faster rate than expected. The main reason is that the material price is 3 ~ 4 times higher than polypropylene and polystyrene. For economic reasons, it is only used in a small number of plastic products. With the cost of polylactic acid (PLA) resin steadily declining, the price difference between polylactic acid and petroleum-based resin tends to be in the 2x range, and the raw material price factors that prevent PLA from entering the market are gradually disappearing.

Polylactic acid resin injection molding coloring, the market can also purchase the use of natural materials for coloring biodegradable inks. By combining a variety of ideas, polylactic acid will see rapid growth in applications such as disposable containers, stationery and daily necessities. In addition, the use of supercritical microfoam injection molding technology allows for a leap in fluidity and allows injection molding of fairly thin molded products. The mission of Fanstar is to master the core technology of injection molding production, communicate and analyze the technology before mold production with customers from the production needs of finished products, so that the mold delivery time is short, the life is long, the mass production is fast and the finished product quality is excellent!
