Meiki – MR Series

MR Series

The MR series from Meiki is the latest instalment of their rubber moulding machine. The expertise used to deliver this pioneering machine is an accumulation of knowledge since its original development in 1962. The slide base design allows quick mould changes and easy insert loading. A hydraulic ejector system is equipped for easy product removal and the vertical clamping and injection units are designed specifically for rubber.

Different Systems

The injection systems are available in two formats. An inline screw system and secondly a screw in plunger system which allows for an increased injection capacity whilst maintaining a low machine height. The screw in plunger type is exclusive to Meiki machines. These can be tailored to the user’s specific machine application.

Meiki – MC-MJ Series

MC-MJ Series

MC-MJ series is Meiki’s injection moulding machine for Sandwich moulding or Marble moulding.

Sandwich Moulding

An ecologically friendly method which offers better utilization of resources and provides environmental protection simultaneously.

Standard Sandwich Mould

Sandwich moulding is a method which uses recycled materials together with new materials stacked atop one another. The recycled material is used for core layer with new material used for a higher quality outer skin.

Foamed Core

By using a standard material for skin layer and a foamed material for the core layer, it is possible to reduce the product’s weight. Sink marks of thick-wall products are prevented and the surface has a soft touch and the foam provides sound absorption.

Gas Barrier

An inner core with gas barrier properties prevents the permeation of gases entering the product. This can be used in food packaging to improve the shelf life of the contents inside.

Stronger High Finish Products

The core material can include fillers such as glass fibre or minerals to increase a product’s strength. Together with a standard material skin to give a high-quality exterior finish.

Marble Moulding

Marble moulding is the injection of two different material sequentially to create a marbled pattern effect. This can be used as a cosmetically to enhance a product appearance.

Meiki – Injection-Press Machine

Injection-Press Machine

Meiki’s Injection-Press Machine allows for easier moulding of larger and thicker products. It simultaneous compresses the material during injection ensuring a more uniform moulding, compared to a conventional clamping method which is unable to mould such large products.

Comparison to Conventional Machines

The Injection-Press machine, unlike conventional machines, delivers this performance by leaving the mould open during the injection phase. It utilises a 4-Axis clamp parallelism and injection volume control to maintain an equal pressure on the material throughout the mould. As a result, the resin flowing pressure and residual stress are drastically reduced, allowing for less warping of flat products. This high performance can be attained even when using edge gate moulds. It even has improved performance with composite/glued mouldings because of its low uniform pressure.

Examples

Under Engine Skirt

Uniform thickness and less distortion/warping
Projection area= 5700cm2
Material: PP
Thickness 1.3~2.0mm
Temperature: 260℃
Centre gate Mould Temperature: 60℃

Injection press moulded Press pressure = 650-ton

Standard injection moulding process Clamping force = 850 ton Injection pressure = 1700kg/cm2

M200C-DM Laptop Chassis

- Glued moulding- Copper foil(35um)
- Material: ABS/PC/PBT+CF15%
- Thickness＝0.9mm

Door Trim

Lower material flowing pressures allows soft inserts to be over moulded.

Glued Fabric insert

Moulding sequence

Mould compression
Mould open and ejection

Meiki Pre-Press System (MPPS)

The Meiki Pre-Press System preloads the material in the screw and barrel using a shut-off valve at the nozzle tip. The screw moves forward closing the check valve on the head, trapping the material inside the barrel at a constant pre-injection pressure achieving an even load density. The screw position after pressurisation is taken as the injection shot volume starting point by the MPPS control system. This enables a constant shot volume to be injected into the mould. Removing any unwanted variation in final product quality.

Meiki – Machine For Disc

Disc Machine

Vistac 1000IID controller developed exclusively for disc machine is adopted. A high cycle time is achievable without compromising high productivity, operability and stability.
This model is designed for CD & DVD moulding making injection compression & injection press process selectable.

This model can make 2 pcs of substrate per cycle at a time.

Model	Unit	MDM-1	MDM-40W	MDM-70W
Screw diameter	mm	28	28	28
Clamping force	Kn/{tf}	393/40	393/40	690/70
Mold opening stroke	mm	190	190	250

The electric direct drive is adopted on injection device.
Adopting a servo motor for injection and screw rotation ensures a highly responsive injection control to reduces power consumption by 70% (electric power consumption because injection unit consumes 70 % of whole power consumption.)

A hydraulic direct clamping, which is inherited from the previous model-MDM-1, enables fast clamping pressure build-up speed for high replication rate and injection compression & injection press process.

MDM-60H, MDM-60Hdual developed.On the basis of MDM-H technology, these models have been developed for twin cavity type of next-generation optical disc.
(MDM-60H: single cavity type, MDM-60Hdual: twin cavity type), and improved machine quality, optical quality, the stability of replication printing quality, and the same quality of both discs substrate.

Mold for optical disc

Mold for CD, DVD and next generation optical disc can be available. Mold parts can be compatible with each other as much as possible. Each user can specify Stamper outer ring and stamper holder specificaions.

Operation board

Larger letter in larger screen than the previous model is adopted. Selecting screen and changing setting values can be done by touching screen. Memorizing molding data and hard-copying screen is offered.

Optical disc production system
Injection molding machine is only a part of whole optical disc production system. Injection molding machine produces substrate with information replicated by stamper taken out by product take-out device from mold, and the other processes include spattering process, bonding process and inspection process. The photo shows an off-line model.

Mold temperature controller itself is built in injection molding machine and is controlled by Vistac alpha controller of injection molding machine ranging within +/-0.1 degree C to setting value. Product take-out device has its compact controller as a part of injection molding machine and can take out substrate within 0.2 sec.
