Manufacturing of rotary-blowing moulds for a global soft-drink company for multiple franchises across India

Project duration: 8 months

Project scope:

– Technical and aesthetic design of a carbonated drink bottle, based on inputs from the customer
– Testing of pilot mould and bottle samples as per international standards
– Manufacturing of moulds for different rotary blowing machines (> 50 moulds)

Project synopsis:

The objective of this project was to design a common bottle for different flavours of carbonated drinks and manufacture moulds for six franchise-bottling operations of a global beverage brand in India. This was what we call a “full scale project”, which starts with designing the bottle, followed by pilot mould trials and ends with the manufacturing of commercial moulds for each franchise.

Bottle designing

· Based on the customer inputs like product application, pack-size and preform weights, we initiated the process of designing the bottle

· With our in-house team of design engineers using state-of-the-art 3D modelling soft-wares, we gave the customer multiple design options, out of which one was finalised.

Pilot mould trials

· Since the design was new and the order quantity was large, we manufactured a pilot mould and conducted trials at our end.

· The bottle samples were tested rigorously as per international standards. Parameters like section weights, material thickness, base clearance, stress crack, thermal expansion were among many others that were checked.

· The final bottle samples were sent to the customer for approval

Mould manufacturing

· The manufacturing of moulds commenced after getting approval from the customer.

· We manufactured moulds for different rotary machines like Sidel SBO, Krones, Sacmi and SIPA. Each machine required 10 to 20 moulds. Although similar in operation, the mould construction varies for each brand. These moulds need to be accurate to the last micron. Only then can these robust moulds produce thousands of bottles every hour for years together with consistent quality.

Moulds for Better Shelf Life of PET Bottles

Before we talk about Shelf Life of PET Bottles let us first understand what does the term shelf life means. Shelf life is the duration of time period measured from the date of manufacture, that a good is likely to endure within its accepted product specification while stocked under defined conditions. Shelf life is characteristically stated in units of months, i.e. 12 months, 24 months, up to a limit of 60 months. The expression “shelf life” and “expiry date” is frequently interchangeably made use of in the industry, as both the terms reflect the same notion: there is a duration of time period where a good is stable and harmless for use. Shelf life/expiry dates suggests the time where a good will work both securely and efficiently. This is the reason why “shelf life testing” is also known as “stability testing”. The total amount of time a product can remain stable under specific environmental circumstances, equates to its shelf life. Now let us understand what shelf ...

Linear Moulds for PET Bottles – Precision & Performance by Awanti Polymoulds

In today’s fast-paced packaging industry, PET bottles have become the preferred choice for beverages, pharmaceuticals, cosmetics, and household products. To meet the growing demand, manufacturers rely on linear blow moulding machines that can produce multiple bottles per cycle with speed and consistency. At the heart of this process lies the linear mould – a critical component that determines bottle quality, accuracy, and production efficiency. What Are Linear Moulds for PET Bottles? Linear moulds are specially designed for high-speed linear blow moulding machines . Unlike rotary moulds, these moulds are long and narrow, with multiple cavities arranged in sequence. Each cavity must maintain high linear accuracy , ensuring uniform bottle dimensions from the first cavity to the last. With advanced design and precision engineering, linear moulds can produce 6 to 12 bottles per cycle , making them an essential solution for large-scale PET bottle production.

How Blow Mold Shell Holders Increase Efficiency in Blow Molding Process

Identifying the Role & Effect In high-speed, high-capacity bottle production, every aspect of the tooling counts. A key feature that non-experts tend to neglect is the shell holder, or mould holder, in the blow-moulding machine. At Awanti Polymoulds, we produce high-accuracy shell holders for rotary machines (for Sidel, Krones, SIG, etc.) which significantly enhance performance, lower downtime and increase output quality. In this article, we’ll explore how shell holders work, what makes a good one, and specifically how they enhance efficiency in blow-moulding processes. 1. What is a Shell Holder? A shell holder is the component in a rotary (or other) blow-moulding machine which secures the mould shell in precise alignment, ensures stability during the blowing operation, and often incorporates cooling features. Without a robust, dependable shell holder, the mould is left to depend only on its mounting fixture and machine clamps — which can affect alignment, cooli...
