Additionalto Synthetic Fiber On Materials Plastic Injection To Minimize Product Defects

Abstract

Plastic injection molding process in the manufacture of air gun components, namely butt stock gun, and pump handles, product defects are still often found, some of the causes include: burning (burning), lack of material (short shots), and cracking products (cracking), this resulting in not achieving production targets and sales targets. The purpose of this research is to find out the root cause of failure of air gun component products. The method in this problem, plastic injection materials need to be added synthetic fibers to get the visual appearance, tensile strength, modulus of elasticity, and the desired hardness, by utilizing recycled material products. The results showed visually the addition of recycled materials and synthetic fibers did not affect appearance, in economic terms the more recycled materials added the cheaper the cost of material procurement. The addition of recycled material weighing 50% of the original material and 2.5% synthetic fiber from the total amount of material to be processed, is expected to increase the tensile strength, modulus of elasticity and desired hardness. Therefore, this addition of fiber obtains a more accurate comparison of product quality and quantity with a lower product defect rate, and is able to reduce production costs.

Pengaruh campuran plastik waste ldpe dan pet bermatrik resin polyester terhadap kekuatan tarik dan struktur mikro

“…Untuk mendapatkan material komposit yang memiliki sifat ringan, berkualitas baik, murah, dan mudah ditemukan, maka penelitian terhadap komposit terus dikembangkan [3]. Penelitian bertemakan komposit yang menggunakan komposisi alami maupun sintetis sering dilakukan, seperti penelitian yang dilakukan [4] dengan penelitian mengenai analisis kekuatan tarik pada Material Komposit dengan Serat Penguat Polimer dengan hasil regangan tertinggi terjadi pada serat PET dengan nilai 1,87 %.…”

Effective and efficient design and manufacture of a plastic waste press machine

“…The village of Madiredo produces 5 tons of garbage every day. The waste is disposed of at the Reduce, Reuse, Recycle (TPST 3R) Integrated Waste Management Site in Bengkaras Hamlet, Madirero Village, where it is sorted and chosen into different categories, including plastic waste, glass waste, bottle cap waste, and used goods waste [1]. The packaging of plastic garbage is still done by hand, which demands a lot of labor, and the outcomes are still less than ideal (messy) (Figure 1).…”
