Meiki – In-cylinder Vacuum Plasticising Device

Vacuum plasticising, Meiki,

In-cylinder Vacuum Plasticising Device

This vacuum plasticising device by the Meiki corporation is built to remove gas and moisture from the material during plasticizing, removing any requirement of pre-drying material before moulding.

The vacmeltor has the capacity to maintain a high vacuum pressure of more than -98kPa while maintaining stable plasticising. The moulding machine`s heating cylinder and screw seals have been an important development for this system.
Vacuum Plasticizing
Plasticising under the high vacuum state contributes to reducing such moulding defects as silver streaks or black spots considerably.

    Meiki – Gas-assist Moulding Device

    Meiki, gas-assist device

    Gas-assist Moulding Device

    During the filling of the mould cavity gas can be applied to the molten layer. This gas-assist device does this to enable the moulding of parts with thicker sections without the normally associated sink marks.

    Cycle times can often be reduced due to the lack of post mould shrinkage simultaneously improving product surface finish and enhancing product quality.

    The ability to mould thicker, wall section parts allow for greater design freedom, something previously unachievable with traditional injection moulding.

      Meiki – Vacuum & Pressure Laminator MVLP Series

      Vacuum & Pressure Laminator, Meiki,

      Vacuum and Pressure Laminator

      This vacuum and pressure laminator from Meiki, the MVLP series, can be used to form layers over irregularly shaped products. Ideal for many application such as thin displays, extremely thin printed circuit boards (PCBs) and integrated circuit (IC) cards due to the way it applies a uniform static pressure.
      Vacuum and Pressure Laminator
      Developed to laminate a photosensitive overlay film over flexible PCBs and their multi-layered counterparts. Which are becoming thinner due to the requirements of higher density circuitry.
      A conventional roller-type lamination has drawbacks such as pressure irregularities, incomplete deaeration, insufficient heating or incomplete embedding. Meki’s device is free from these problems since it applies uniform static pressure over the entire surface of the film.
      Furthermore, an adjustable pressure enables lamination of PCBs with thick circuit patterns. By increasing the pressure uniformly and controlling at a higher temperature, PCB’s with irregularly shaped products can now also be laminated.

      Differences Between the MVLP and a Roller Type

      Please observe the two diagrams below, illustrating the differing work method between our MVLP series and the roller type laminator.

              Meiki – MC-MJ Series

              MC-MJ Machine, Meiki,

              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,

                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.

                • Uniform thickness and less distortion/warping
                • Projection area= 5700cm2

                4. 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.
