The World

Moving to a more sustainable and healthy future, the world has decided to invest on researches to make good use of waste vegetable oil rather than letting them clog the drains and hence, polluting the environment. One of the useful projects which uses these waste cooking oil is to synthesize polyols. Solidifying the polyols using cross linker produces a Sustainable Polymer (SP). These SP are compounded with the High-Density Polyethylene (HDPE) by melt-mixing using injection molding machine. Injection molding is capable of producing many useful products. Therefore, aiming to analyse the processing conditions of injection molding, the corresponding mechanical properties of the compounds produced were examined. The results indicated that increasing the SP content will increase the toughness of the compound if compared to neat HDPE. It was concluded that the processing temperature and composition of SP will both influence the quality and mechanical behavior of the injected polymer compounds.

Driven by the need of growing to a more sustainable and environmentally friendly future, this research is started by mixing in-house produced biorenewable polymers (BP) from waste cooking oil with the standard low density polyethylene (LDPE) and high density polyethylene (HDPE) via melt-mixing at low ratios. These mixtures are then compounded via injection molding to produce tensile samples. By using the quality of individual compounds injected, the parameters obtained for all ratios of LDPE/BP were the same with neat LDPE whereas some adjustments were required for the HDPE/BP compounds. The corresponding mechanical behaviors of each ratio were also examined and the results showed that both tensile strength and strain of the LDPE/BP were better than neat LDPE. On the other hand, increasing the BP content in HDPE/BP will increase the toughness of the compound if compared to neat HDPE. Therefore, not only does the presence of BP provide renewable properties, but it also improves the mechanical properties. Moreover, the processing temperature and composition of BP will both influence the quality and mechanical behavior of the product made. Thus, this study may aid any intention on processing these in-house produced polymers by injection molding.

This research is started by mixing in-house produced sustainable polymers (SP) from waste cooking oil with the standard low density polyethylene (LDPE) via melt-mixing at low ratios. These mixtures are then compounded via injection molding to produce tensile samples according to ISO 527 (5A). The parameters used in injection molding were initially set to follow the parameters of neat LDPE. Fortunately, by using the quality of individual compounds injected, the parameters obtained for all ratios were the same with neat LDPE. The corresponding mechanical behaviors of each ratio were also examined and the results showed that both tensile strength and strain of the LDPE/SP were better than neat LDPE. Therefore, not only does the presence of SP provide biodegradable properties, but it also improves the mechanical properties. It was concluded that the processing temperature and composition of SP will both influence the quality and mechanical behavior of the product made. This study may aid any intention on processing these in-house produced polymers by injection molding.

This chapter discusses the management of waste cooking oil (WCO) in a sustainable manner in order to protect the environmental pollution. Increasing consumption of edible oils worldwide leads to generation of substantial amount of waste cooking oil (WCO). While WCO is not considered toxic, large amount of WCO can contribute to environment pollution if not being handled properly. The huge generation of WCO in the world creates problem of collection, treatment and disposal. Due to its chemical features, the recycling of WCO not only provides a renewable feedstock for producing biofuels and bio-based products, but also alleviates environmental pollution arising from its improper handling. This chapter also provides an overview of some recent approaches in WCO recycling and applications.

Among different natural oils, recycling of waste vegetable oils from palm oil is widely explored for polyol synthesis to prevent pollution of waterways and clogging private and municipal drain systems, restaurants and other food preparation. The polyol is solidifying using cross linker and known as Sustainable Polymer (SP). SP is compounded with High-Density Polyethylene (HDPE) and Low-Density Polyethylene (LDPE) by melt-mixing using an injection molding machine. The effect of polymer compounding ratio on the mechanical properties was studied by tensile test. The result indicated that increasing the SP content in LDPE or HDPE was responsible to the reduction of tensile strength and elongation at break of the samples, if compared to pure thermoplastic LDPE and HDPE. This can be verified by increased in SP amount which gave a significant increase in density of the polymer compounds. Morphological of tensile specimens’ surface fracture is revealed the homogenous characteristic with high compatibility properties of sustainable polymer with its compounded polymers.

High Energy Consumption

As is known to all, domestic productions of injection molding machine are huge and exported to all over the world. However, the production can only occupy the low-end markets because of its high-energy consumption and low molding precision. Besides the problems of mechanical components, the main reason led to such results lie in the its too backward hydraulic system. By comparing domestic traditional hydraulic system with foreign new hydraulic servo system, this paper focuses on the analysis of the characteristics of foreign new hydraulic servo system and verify the results by experiments based on the upper two different hydraulic system. Through this paper hopefully can it provide some practical directs to the design of domestic new hydraulic system.
