JS Series

JS Series Upgraded Plastic Injection Moulding Machine

YAN HING GROUP didirikan di Hong Kong sejak tahun 1950 dan telah berpengalaman lebih dari setengah dekade dalam produksi mesin plastic injection. YAN HING GROUP telah bekerja sama dengan PT. EKA MAJU MESININDO lebih dari 30 tahun dalam memasarkan produk-produk YAN HING di Indonesia secara eksklusif. JS series adalah mesin plastic injection dengan kapasitas lebih besar dan komponen yang ditingkatkan (upgraded). Biasanya digunakan untuk mencetak barang ukuran besar.

Clamping Unit

Highly accurate and rigid nodular graphite casting steel platens designed through CAE finite element analysis ensure optimal requirement of clamping

Five-point vertical double toggles and chrome-plated high tensile tie-bars give stable platen movement and sufficient clamping force

Clamping speed is largely increased over 80% by adopting differential hydraulic circuit

Extended daylight opening and enlarged platens allow accommodation of bigger moulds

Electrical, hydraulic and mechanical safety devices are all employed to ensure safe operation

Prompt and accurate change of every mould closing/opening stage ensures smooth mould travelling and mould protection

The application of self-lubricating bearings in platens, cylinder rods, guide rods, etc. can largely eliminate wear of mechanical parts and thus prolong machine life

Injection Unit

Nitrided screw and barrel

Productivity can be increased by high speed and high pressure injection and plasticizing

Double hydraulic carriage cylinders ensure secured contact between nozzle and mould and prevent nozzle leakage

The design of T-shape slide-way for movement of injection unit results in highly stable operation

Special design of screw check valve and digital screw back-pressure control allow the best plasticizing result in both mixing and melting

P-3 Controller

European-made and specially designed computerized controller Plastronic-3, P-3, shows all operation parameters and allows memory storage of 500 moulding data sets. It also gives warning messages in case of malfunction

8 inches large LCD monitor with Chinese/English character interchangeable display

Direct input of pressure, speed, position, time, moulding temperature and functions

6-stage setting for injection pressure, speed and position

3-stage setting for injection holding pressure, speed and time

2-stage setting for plasticizing pressure, speed and position

5-stage setting for mould open/close pressure, speed and position

2-stage setting for ejection pressure, speed and position

Highly accurate potentiometers monitor mould, screw and ejector position

Injection volume detection and screw prevention of cold start

Built-in PID temperature control program and solid state relays in heater circuit give accurate moulding temperature and durable control circuit

Independent heater temperature malfunction monitoring device to prevent barrel overheat

Computer sequence safety protection monitoring to prevent abnormal mould closing

Sequence control for accumulator, automatic dual core pulling, unscrewing device, dual air ejectors"photo-cell detector, extractor, etc"

Pre-setting product count

Injection and mould data can be saved in computer or memory card through USB

Hydraulic Control

Use of highly efficient Japanese-made variable displacement piston pump can save energy consumption up to 50%

High pressure and high speed performance can be achieved by employing large displacement pump driven by high power electric motor

Use of imported hydraulic valves ensures highly precise moulding

Hydraulic blocks are mounted close to the actuators to reduce discrepancy

All-time hydraulic oil filtering
