  3. MA II/h Hydraulic High-Performance Machine Market Market Situation Along with current developments, injection-molded products are changing from single to multiple, and from simple to complex. Facing an increase in thin-wall and high-precision molds, existing hydraulic machines cannot anymore meet the requirements. Besides, with margins narrowing, manufacturers have to increase their efficiency and to close down outdated production facilities. Following the development of the injection molding industry, the market becomes gradually more subdivided and the competition more obvious and fierce. The only way out is the special applications market. Machine technology with added value and obvious characteristics Machines for special applications • Industrial scale production, meeting the basic requirements of the market Standard Machine

  4. MA II/h Hydraulic High-Performance Machine Market Main Application Areas ● Universal Machine, Different Choices for Different Requirements The MAII/h Series comes with an injection speed range of 130mm/s to 150mm/s, the MAII/p packaging series comes with a range of 180mm/s to 230mm/s ●Packaging, Multi-Cavity, Thin-Wall Cups, ice cream boxes, lunch boxes, bowls, food containers, cutlery, closures, pots, cell phone battery cases, CD boxes, bank cards, medical packaging etc.

  7. MA II/h Hydraulic High-Performance Machine Characteristics Higher Injection Speed Overall increase of injection speed compared to common IMM, the same clamping unit can be combined with different injection units to reach different injection speeds. This way, technology to the point can be provided. 1100h(Injection speed about 140mm/s) 750p(Injection speed about230mm/s) Example: MA2700II

  8. MA II/h Hydraulic High-Performance Machine Characteristics Plasticizing Unit with High L/D Ratio, High Speed and High Efficiency The plasticizing unit of the MA II/h (p) uses a high-speed nitrided screw and a nitrided barrel with a DMG front structure

MAII/h Hydraulic High-Performance Machine Characteristics Multi-Spline Coupling Plasticization Unit Plasticizing Motor ● Screw and motor are connected by a multi-spline connector for a more stable and reliable operation. Plasticizing Bearing Shaft Screw grommet Multi-Spline Connector Screw coupling lock Screw

  10. MAII/h Hydraulic High-Performance Machine Characteristics Double Injection Cylinder and Double Ended Shafts; Strengthening of Piston Shafts ● Double Ended Shaft Design： — Ensures stability during high-speed injection and reduces return oil pressure ● Piston Shaft Strengthening： —One-piece piston shaft； —Thicker diameter； — Avoids the impact of stress concentration of the thread retract groove section — A pressure relief groove was added to the tail section to minimize the fracture risk of the piston shaft

  11. MA II/h Hydraulic High-Performance Machine Characteristics Linear Guide Rails with Linear Bearings, Manual Lubrication ● Advantages： — Minimum friction force in motion and downtime; very good ability to follow; increases the system’s response time and sensitivity； — Energy saving because of significant decrease of driving power — High positioning accuracy and high repeat positioning accuracy； — Gapless movement; Increase of movement rigidity of the mechanical system

  12. MA II/h Hydraulic High-Performance Machine Characteristics Plasticization Bearing Shaft with High Quality Bearings; Designed for a Long Service Life ● All bearings of the plasticizing shaft have been enhanced in their design which has substantially increased the dynamic load capacity as well as the service life. This way the service life of the main bearing could be increased by five times; ● At the same time the lubrication and maintenance of the plasticizing shaft bearings have been improved. The lubrication grease must be changed annually, this way an excellent operation condition can be guaranteed.

  13. MA II/h Hydraulic High-Performance Machine Characteristics Clamping Unit Strengthening of moving platen (central force distribution), extension of foot towards front, reduction of stress and strain of the platen Using Bronze with Graphite bushes, reducing the gaps between the bushes and the toggle link pins; similar to full-electric IMMs Optimization of clamping curve Strengthening of fixed platen; extension of foot towards front; improvement of fixed platen nut and gland. 1 Improved mold adjustment structure Strengthened tie-bars, guides fitted with bronze and graphite bushes Sliding bronze and graphite wear pad mounted from the side of the platen.

  14. MA II/h Hydraulic High-Performance Machine Characteristics Clamping Unit: Larger Clamping Parameters, Bigger Mold Area ● Clamping Unit: Increase of space between tie-bars for more space to install larger molds and to unload larger numbers from the mold as long as the clamping force is sufficient

  15. MAⅡ/h Hydraulic High-Performance Machine Characteristics Measurements Taken to Solve Issues With Broken Tie-Bars Phenomenon: Tie-bars happen to break at the connection between tie-bar and screw nut during short-cycle operation in common machines Causal analysis: 1. The stress concentration on common tie-bars and screw nuts is obvious 2. As the common fixed platen is not that solid, the deformation of the platen will lead to shearing force which has an impact on the tie-bars. 3. Wear on the rear platen’s mold adjustment nut pad structure, due to insufficient lubrication leads to wear and tear and intensifies the impact and stress on the tie bars, toggle pins and bushes with the mold opening and clamping. 4. Wear and tear of the rear platen’s foot wear pads leads to swinging of the moving platen and increases the wear impact on the machine.

  16. MA II/h Hydraulic High-Performance Machine Characteristics Because of a larger impact inertia during mold opening and clamping within the short cycle high-speed molding process, the deformation of the platen and the tie bars is relatively high. As the fixed platen of the MA II/h Series was made thicker after a Finite element analysis, the deformation of the fixed platen as well as its impact of the tie-bars could be decreased.

  17. MA II/h Hydraulic High-Performance Machine Characteristics Optimization of the Moving Platen ● As a central force distribution structure design is applied on the moving platen, the central mold area of the moving platen almost don't face any deformation during mold clamping, the results are: — decrease of platen deformation index, decrease of mold deformation, prolongation of mold service life; — even distribution of clamping force, increase of molded products’ precision; — even distribution of stress on mold, decrease of parting-line flashes on molded products and uneven wall-thickness; — 10%-30% of clamping force can be saved compared to similar operations

  18. MA II/h Hydraulic High-Performance Machine Characteristics Tie-Bar Anti-Fracture Optimization Improvement Measurements ● Thickening of tie-bars, decrease of tensile stress; ● Thickening of tie-bar seal ring; ● Double pressure relief groove design; ● Suspension nut design for tie-bar nuts; ●Increase of tie-bar material quality Fixed platen and tie-bar matching structure

  19. MA II/h Hydraulic High-Performance Machine Characteristics Improvement of Mold Adjustment Structure ● Better control of space between nut and nut pad as well as decrease of axial clearance at the mold adjustment nut, leading to minimization of impact at tie-bar screw nut ● At the same time, improvement of lubrication hole position, change to greasing at both sides of the nut pad, more convenient greasing

  20. MA II/h Hydraulic High-Performance Machine Characteristics Rear Platen/ Moving Platen Glider Improvement Improvements: ● Changes on the foot padding of the moving/rear platen as in the graphic, side-way fixing, also a self-lubrication system has been added.
