EXTRUSION BLOW MOULDING

MSC SERIES

HOME > Products > MSC SERIES
The MSC SERIES consists of the MSC-4, MSC-6 and MSC-6-s models.

A unique extrusion blow moulding system in the market allowing for the manufacturing of plastic containers with calibrated necks of up to 10 litres in a continuous movement rotary unit. The moulds are situated radially in the wheel. It offers great flexibility for the manufacturing of containers of very diverse shapes and sizes.

  • CHARACTERISTICS

    • Easy and economic adaptation of the view-stripe as well as multi layer configurations.

    • Container capacity of up to 10 litres.

    • Maximum mould number: 6 (can operate with 2 or 3 moulds).

    • Calibrated necks (or occasionally, “false” calibrated).

    • Output: up to 1,600 b/h.

    • Comprehensive control system, including a parison thickness regulator, with an interface for visualizing process parameters and a statistical production control.

    • Integrated deflashing unit: minimum tools required (only one punch station and its support).

    • Integrated transfer system for the container to the deflasher.

    • Centralized lubrication system.

    • Automatic start up.

  • ADVANTAGES

    SAVINGS OF RAW MATERIAL

    Having a single head, regardless of the number of moulds, provides maximum uniformity in the containers, leaving their weight within a very narrow range. This allows reducing the average container weight.

    LOW ENERGY CONSUMPTION

    A reduced quantity of energy is required to maintain the wheel in rotation and to ensure the final clamping of the moulds. The single head also helps minimize energy consumption, reducing the number of heaters and heads to a minimum.

    FLEXIBILITY

    Characterized by maximum flexibility, allowing for the combination of different sized containers while maintaining reduced scrap.

AUXILIARY EQUIPMENT

Because the PEAD blow moulding machine is the basis of a bottle manufacturing line, it is necessary to have access to auxiliary equipment that may be optionally supplied as part of a turnkey project.

CLOSED CIRCUIT FOR MATERIAL HANDLING TO FEED THE BLOW MOULDING EQUIPMENT

Includes:

  • Grinders to granulate the scrap generated during the process.
  • Raw materials mixing system, masterbatch and regrind material.
  • Feeding systems of the mixture to the blower machines.

EQUIPMENT TO PROVIDE THE NECESSARY FLUIDS

  • Low pressure air compressor for blower and pneumatic drives.
  • Water cooling systems for moulds and other machine services (feeding zone, gear box, etc.)

OTHER EQUIPMENT

  • Leak testers.
  • Vision systems for control of the produced container.
  • Wrapping system and/or palletizing of empty packaging, etc.
  • Transport systems to silos or other storage systems.
  • Dehumidification systems.

Urola supplies these and ensures their installation through a turnkey concept, taking responsibility for the operation of the line.

MULTILAYER CONTAINERS

Having only one head, regardless of the number of moulds, makes Urola’s rotary machines ideal for multi-layer containers requiring multi-layer heads.

Multiple layer packages capabilities

Multiple layer packages advantages

Certain products require multiple layers in the packaging due to demands created by the following situations.

Barrier properties to protect the product

  • To prevent ultraviolet (UV) light from penetrating inside the container and damaging the properties of the product. The typical configuration consists of 3 layers, the internediate, being black one. Used for dairy applications that require long duration.
  • To avoid the penetration of oxygen into the packaging where it may cause oxidation of the product, 6 layers are typically needed, as the barrier layer requires adjacent layers with adhesive properties (sauces, mayonnaise, juices, ketchup, some dairy products with added vitamins).
  • To prevent the product properties from exiting the packaging (chemical products, etc.). 2 layers are utilized.

Use of recycling

  • To take advantage of post-consumer recycled materials. Three layer configurations, with the recycled layer being located in the interior.

Masterbatch reduction

  • To minimize the quantity of “Masterbatch”, in cases where the cost is high. The “Masterbatch” is added to the external layer which is thinner than the internal layer.

Coextrusion technology

  • To manufacture multi-layer containers it is necessary to install coextrusion systems, whereby the different extruders simultaneously feed the head.
  • It is vitally important that the layers maintain consistency both longitudinally and radially to minimize the amount of barrier material.
  • In the case of Urola’s rotary machinery, because there is only one head, regardless of the number of moulds, the multi-layer configuration is considerably simplified while at the same time, the required consistency is guaranteed.
  • For this, the highest quality multi-layer heads in the industry are used.

CHECK OUT OUR MOULDS

MOULDS

The blow mould plays a fundamental role for the production of bottles, and that is why at Urola we integrate the complete process.

We advise, design the container and mould, manufacture the mould, manufacture samples and provide the best possible after-sales service.

ADVICE

Our service begins with a customer consultation regarding container design, taking the following factors into consideration::

  • The product to be packaged.
  • Aesthetic factors.
  • Suitability for the container manufacturing process.
  • Technical characteristics required of the container.

CONTAINER AND MOULD DESIGN

We have the most appropriate means to develop the designs of the container and mould, both highly qualified technicians and the most powerful computer tools.

MOULD MANUFACTURING

We use 5 axis CNC Machining Centers and other auxiliary machines for the manufacture of moulds with the highest quality.

SAMPLE MANUFACTURING

This service is covered by Urola when it is required to determine the validity of the container when it is a new packaging development.

AFTER SALES SERVICE AND PREVENTIVE MAINTENANCE

We accompany the customer in the maintenance of the moulds during their useful life to ensure that the conditions of the process are maintained in optimal conditions.

For this we replace worn parts, repairs, check air outlets, check cooling circuits, etc.

A cooling system is integrated within the very mould. Moulds are manufactured in duralumin with stainless steel, treated neck adjustments.

We do even more!

Urola Solutions develops advanced solutions for the packaging manufacture with blow moulding technology, providing added value to end users.
