Injection molding machine

Injection molding machine which consists of injection unit,
plasticizing unit, clamping unit and ejection unit, and isused for manufacturing plastic products.

All-electric injection molding Injection molding machine which is operated by electricmachinepress. All of 4 servo-motors for injection unit, plasticizingunit, clamping unit, and ejection unit are directly
electrically driven. All-electric injection molding machineis designed by opened control system.

Hydraulicinjection

machinemolding Injection molding machine which is operated withhydraulic press by the oil pumps. Hydraulic injection
molding machine is designed by closed control system.

Power regeneration

To regenerate electric power efficiently by kinetic energy atdeceleration of motors.

F. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
Reduction ratio of specific electricity consumption of the project injection molding machine tothe reference injection molding machine (RR) is provided as a default value in thismethodology and is conservatively set ex ante in the following manner to ensure the netemission reductions.
Specific electricity consumption (SEC) is an electricity consumption of injection moldingmachine to manufacture one unit of plastic product. SEC can be estimated from design
specification of injection molding machine.

JCM_ID_AM025_ver01.0
Sectoral scope: 03
1. The hydraulic injection molding machine is currently available and commonly used in theIndonesian market. Therefore, it is determined as a reference injection molding machine.
2. SEC data of all-electric injection molding machine (SECPJ) and hydraulic injection
molding machine (SECRE) to manufacture several types of plastic products have beencollected from the manufacturer of injection molding machine.
3. Values of RR are derived as a ratio of SECPJ to SECRE to manufacture the same type ofplastic product. The maximum RR value amongst the RR values derived as above isselected and set as a default RR value in a conservative manner to ensure net emission
reductions, which is described in Section I of this methodology.
