Description:

1, Special design to avoid noise
2, Save 30-50% energies, Especially for long produce circle productit will save more.

1. Introduction

 

Plastic injection molding machine is the equipment to processthe heated thermoplastic or thermosetting plastic moldingproducts.

RonGAN RAM-IM injection series introduced injection volume of100-30000 m3, clamping force for the 70-3000 tons plastic injectionmolding machines which with different control-level. The product isCAD, CAM technology to optimize the design and technology tooptimize the design and high-precision automatic CNC machining,precision machining parts, or filtering are used by the world''sfinest brands of components, and in accordance with the stricttechnical requirements for production, assembly, adjustment effectfrom. Product has novel structure, stable performance, highefficiency and other notable features.

 

A,  RAM-IM-KP high-speed auto PET preformproduction line 

 

 

a) Thehigh-speedauto PET preform production line equipped with specialdesigned barrel and screw, and the line with  effectiveand perfect plasticizing performance;

b) Hydrauliccylinder with pressure holding system, deeply reduce the productioncycle time; 

c) Doublehydraulic system, which help achieve the mould opening, clamping,preform ejecting for clamping unit and the plasticizing forinjection unit can be done in the same time to reducethe product forming cycle time;

d) Preform taking-out system canachieve preform taking and cooling at the same time, reducethe product forming cycle time.

 

B,   RAM-IM-VP Energy SavingInjection line

 

 

 

a) The energysaving injection line can ave 30-50% energies than the normaltype,  specially for the long produce circleproduct;

b) Theline equipped with highquality variable pump (YUKEN / VICKERS), runningstable;

c) Special design to avoid noise;

d) Circlefilting system can ensure the hydraulic elements normalrunning;

e) Cooling watersaving system.

 

C, RAM-IM-TS ThermosettingInjection Molding Line

 

 

a) Thethermosetting injection line equipped with high quality mouldinsulation device;

b) Speciallyprocessed bimetallic anti-wear screw;

c) Precisetemperature controller, stablely heating;

d) Professionalcontroller program suit thermsetting injection.

3. Equipment Composition

 

A. Clamping System

Arrange obliquely five -point and elbow type structure.Optimization design on parameter of the computer. Finite -elementanalysis is applied to design the plates.

The unit also functions of low pressure mold protection withextra sensitivity. Machinery, Eiectric pair of safe protectionfunction to insure the safety. 

 Oil motor drive the gear to adjust mould. The moving aheadsimultaneously is good, and can adjusting the mould automaticallyaccording to the pressure set up, very convenient and reliable.

 

 

B. Control System

Adopt imported computer which special for injection machine .TheFunction is powerful and controlled by CPU , improve the speed incontrol system and the alarm on over-tempreture. lmprove theworking speed of machine.

  

C. Injection System

 

Double guid ing rod supporting.Dual-cylinder balance injectionsystem, Single-cyl inder push and draw back setting. Multi -stagepressure & speed injection, One-str ing hydraulic motorsetting. Super quality steel screw stem mixed with chrome,molybdenum and aluminium and barrel disposed by nitrogen .Su itablefor every kinds of plastic raw material.

 

 

D. Hydraulic System

 

Adopt imported advanced hydraulic components.
