1. TITLE: ENERGY ANALYSIS IN PLASTIC INJECTION MOLDING MACHINE TEAM: DYNAMITE UNIVERSITI UTARA MALAYSIA Choo Chi Sien (Leader) Chew Lim Sim Ooi Chung Pang Contact: chisien1130@Live.com / 017-558 0700chisien1130@Live.com

2. OBJECTIVE OF PROJECT  To assist owners and operators of plastics manufacturing facilities select different injection molding parameter  To save energy and improve cost effectiveness of their operations  To maximize the integration of energy efficiency  To act as a guideline for industry to reduce cost of production & electrical consumption  To reduce manufacturing costs  To increase business competitiveness  To reduce carbon emissions SIGNIFICANT OF PROJECT

3. Mold Close -> High Clamp -> Injection -> Holding Pressure -> Plasticizing -> Cooling -> Mold Open -> Ejection The process went through 8 operating steps…

4. SOLUTION!  Plasticizing stage consumes high electrical energy = high carbon emission WHAT’S PROBLEM OF THE PROCESS? Set different set of machine parameter Power On Machine Current logger record the data Calculate Total distribution of energy (First stage) Energy Map formed (Second stage) Optimize the data (Final Stage) mm/s, Pa

5. SCOPE OF PROJECT Constant variable: Size of the mold, Clamping force Nissei NEX500 Thermoplastics (polycarbonate) UniMap Electricity Input: 415V Kyoritsu KEW5020 Current Logger Injection velocity (mm/s) Injection pressure (psi) 265°c ~ 315°c
