Definitions

Injection molding machine

Injection molding machine which consists of injection
unit, plasticizing unit, clamping unit, and ejection unit andis used 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 directlyelectrically driven. All-electric injection molding machineis designed by opened control system.

Hydraulic injection molding

Injection molding machine which is operated withmachine

hydraulic press by the oil pumps. Hydraulic injection
molding machine is designed by closed control system.

Power regeneration

An electric power that makes it possible to regenerate
electric power efficiently by kinetic energy at decelerationof motors.

Summary
reduction Installation of all-electric injection molding machine with afunction of power regeneration leads to reducing electricity
consumption by the oil pumps which are used for reference
injection molding machine (hydraulic injection moldingmachine), and consequently GHG emissions.

Calculation
emissionsofreference Reference emissions are calculated with the electricity
consumption of all-electric injection molding machine,
reduction ratio of electricity consumption and CO2 emission
factor for consumed electricity.

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 to
the 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 net
emission reductions.
Specific electricity consumption (SEC) is an electricity consumption of injection molding
machine to manufacture one unit of plastic product. SEC can be estimated from design
specification of injection molding machine.
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.
