Specialized Molding Solutions

Nissei ASB has developed many specialized techniques enabling enormous flexibility of production.

Ultra-Narrow Neck
  • Technology
    Ultra-Narrow Neck
  • Description

    By utilizing a special preform molding technique combined with re-shaping of the preform at the conditioning station, our ASB Series models can mold containers with a neck bore diameter as low as 2.5mm suitable for very small containers.

Thick Wall & Base
  • Technology
    Thick Wall & Base
  • Applicable Series

    ASB

  • Description

    Using special injection cavities that change shape during injection molding, base thicknesses of 10mm or more can be achieved while maintaining perfect clarity. The finished visual impression is a PET container that is indistinguishable from glass. Combine this with a thick wall to produce the extreme high quality for premium cosmetic products.

Injected Shoulder
  • Technology

    Injected Shoulder

  • Applicable Series

    ASB

  • Description

    Where a specialized container shoulder is required having exceptional detail for market appeal or precise capping, the shoulder can be molded as a flange on the preform in the injection cavity.

IBM/Sharp Corner Molding
  • Technology

    IBM/Sharp Corner Molding

  • Description

    ASB’s conventional 4-station molding Injection Stretch Blow Molding (ISBM) process can be converted* to the 2-station Injection Blow Molding (IBM) process. With a suitable mold, this process is especially useful for molding small bottles in a variety of materials that feature extremely sharp corner radii of 0.24-0.97mm, even in PET.
    ※ with compatible models

Tilted Neck
  • Technology

    Tilted Neck

  • Applicable Series

    ASB

  • Description

    For baby feeding bottles this specialized container design provides distinct advantages at feeding time. The same technique can be used to mold containers with eye-catching visual appeal to aid in product marketing.

Stackable
  • Technology

    Stackable

  • Applicable Series

    ASB/PF/HSB

  • Description

    By blow molding with a deeply inset base, containers can be stacked directly on top of each other reducing volume for storage and transportation and reducing interlayer packaging materials.
    ※ Some models may require option parts.

Deep Pinch Grip
  • Technology

    Deep Pinch Grip

  • Description

    With ASB’s deep pinch grip technology, containers can be molded having handle grips much deeper than has ever been possible before. The result is the ability to mold large containers that can be comfortably held by everyone.

Front Parting Line
  • Technology

    Front Parting Line

  • Description

    Thanks to our high quality mold manufacturing techniques, parting lines are virtually invisible. By designing oval containers with the parting line on the front / rear face, cavitation and productivity can be raised by up to 80%.

Extreme Oval
  • Technology

    Extreme Oval

  • Description

    Preforms can be molded using ovalized injection cores or cavities. Preform temperature can be modified by use of ovalized conditioning station components (ASB), or Preferential Heating (PF). As a result, high ovality ratios are easily achieved while maintaining perfectly equal wall thickness.

Champagne Base
  • Technology

    Champagne Base

  • Applicable Series

    ASB/PF/HSB

  • Description

    Deeply dished bases for pressurized containers can be easily molded using the built in “bottom mold delay” of the molding machine with an appropriate mold design.
    ※ Some models may require option parts.

Split Type Conditioning Blow
  • Technology

    Split Type Conditioning Blow

  • Description

    An ASB Series machine can utilize split type conditioning blow in order to stretch blow mold polypropylene narrow necked containers with increased molding stability. The technique can also be used to more easily mold very thick walled PET containers.

Handle Molding
  • Technology

    Handle Molding

  • Description

    A variety of handled bottles can be molded including post-molding and in-mold types (ASB/PF) and integral (PF). By applying spot cooling in the conditioning station, the preform is stretch blown to the ideal condition for stable molding of handled containers.

PET Can
  • Technology

    PET Can

  • Applicable Series

    ASB

  • Description

    The ability to injection mold a very thin flange means the container can go through the standard aluminium can lid crimping process. A transparent container enhances the product appeal.

Off-Center Necks
  • Technology

    Off-Center Necks

  • Description

    Household trigger spray and similar containers are often designed with necks that are off-center. At ASB we have many experiences with this type of container design and can offer off-center ratios as high as 2:1 (standard) , 7:3 (specialized).

Fixed Neck Orientation
  • Technology

    Fixed Neck Orientation

  • Description

    Since the neck of the container is held throughout the molding process (ASB), the neck will always be in the correct orientation. Users of PF Series machines can achieve the same result with the optional neck orientation system.

Super Light Weight/Bag In Box
  • Technology

    Super Light Weight/Bag In Box

  • Applicable Series

    ASB

  • Description

    Extreme light weight containers can be molded to allow the body to collapse to eliminate air space, for storage prior to filling or efficient compacting of recycled materials.

Asymmetric Parting Line
  • Technology

    Asymmetric Parting Line

  • Applicable Series

    ASB/PF

  • Description

    ASB’s superb quality blow mold manufacturing allows complex container shapes with undercuts to be molded by designing the blow mold parting line off the normal axis.

Complex Neck Design/Very Short Necks
  • Technology

    Complex Neck Design/Very Short Necks

  • Description

    Since the preform is custom designed for the container, the end user can specify virtually any neck that is moldable (ASB/PF). In ASB Series machines, the neck of the container can be as short as 3mm allowing greater flexibility on cap design and lighter weight.

Zero/Minimum Support Ring
  • Technology

    Zero/Minimum Support Ring

  • Description

    Containers molded in ASB Series machines do not require any support ring as the neck is always firmly held by the molded threads. In PF Series machines, the support ring diameter can be as low as 2mm greater than the preform diameter. Weight can be saved and the appearance is enhanced.

Bottle-to-Bottle Recycling
  • Technology

    Bottle-to-Bottle Recycling

  • Description

    With the simple addition of a specially designed PET resin dryer, ASB’s full range of machines can mold suitably re-processed post-consumer resin directly into many containers for a wide range of applications, contributing toward a cleaner environment and cost reductions in raw materials.
