Plastic injection moulding manufacturing

Nowadays plastic is used to make a great variety of items and components. Some of them have the most peculiar shapes and dimensions, and obviously require millimetric precision that can be achieved through the use of proper moulds. As a plastic injection moulding manufacturing company, Idea Stampi solves your need and want by delivering you all the kinds of moulds you need.

Injection moulding is one of the most common methods for manufacturing plastic parts and components because it can support either en masse and niche scale production with the utmost precision and at quite low rates.

Plastic injection moulding manufacturing for en masse production

Among the characteristics of injection moulding we can cite its versatility which allows this technique to fully satisfy the requirements of large, medium, small, and niche production.

Plastic injection moulding manufacturing at Idea Stampi covers all these three areas:

Plastic injection moulding manufacturing for en large-scale production

This kind of production definitely requires the utmost attention during the manufacturing of multiple-impression moulds. As high production volumes can easily wear out the moulds, plastic injection moulding manufacturing must pay particular attention to thermal treatment, normalised products such as those by Hasco/Meusburger, and ball bearing sliding systems that make it easy and quick to change and remove the moulds inside the machine.

Plastic injection moulding manufacturing for medium-scale production

Does your annual consumption range between 50.000 and 100.000 parts? Here are Idea Stampi’s moulds with 2/4 impressions!

In manufacturing these injection moulds we always keep in mind our purpose, that is delivering you long-lasting products characterized by utmost precision, high quality and lower costs.

Plastic injection moulding manufacturing for small-scale production

Pilot moulds are the most appropriate for manufacturing products in small or niche series. The dimensions and the characteristics of each mould are to be decided on the base of the product to make, but we can say that the moulds are generally made of hardened and tempered steel or aluminum.

What kind of moulds are you after?

Plastic injection moulding manufacturing step by step

Delivering the types of moulds described above requires a certain degree of study as plastic injection moulding manufacturing is a process to be carried out through different steps:

#1 Design and co-design

Upon request, we co-design the mould you need along with you so we can discuss the aesthetic aspect and the technical details.

After that, our engineers start the actual plastic injection moulding manufacturing process by using state-of-the-art technologies such as CAD/CAM/CAE and VISI Flow systems to accurately evaluate even the tiniest details of the moulds-to-be.

#2 The actual construction

After every little detail has been defined we are ready to concretely give form to the mould. Our greatest advantage is that we use the same 3D model, which allows us to avoid data transcription errors.

To complete the production cycle, we conduct in-house final testing by using presses from 25T to 350T.

#3 Pre-series production

When a mould has been approved and die cast, we can proceed with the actual plastic injection moulding manufacturing.

This basically is a pre-series service we offer to verify the usability of the moulds.

How injection moulding manufacturing works. During this process a thermoplastic material in granular form is fed through a hopper into a heating barrel and driven through the gates and into the mould by a large screw. This one applies a certain pressure for the duration of the cooling time, then it is withdrawn. Finally, the mould is opened and the plastic product ejected.

In need of pilot moulds or mould maintenance?

If so, we can help you. Our offer includes two further services:

• Production of pilot moulds – before starting any injection moulding manufacturing process you may want to check some parts of the mould or its feasibility: well, prototypes and pilot moulds are the easiest way to reduce investment risks, especially when dealing with multi-impression moulds
• Mould maintenance – it includes several services ranging from standard cleaning to the reconstruction of worn parts also of moulds produced by other companies

The benefits of plastic injection moulding manufacturing

Injection moulding is one of the most versatile processes for manufacturing plastic items and components for as different industrial sectors as automotive, household appliances, electronics and electromechanical, personal care, food, industrial automation.

In fact, plastic injection moulding manufacturing provides many benefits indeed:

• It is a straightforward process, but it allows as many customization as you desire
• It is one extremely suitable for scale production en masse
• It has very low manufacturing costs one the initial costs have been paid
• It produces slow scrap rates
• It is very repeatable
