Manufacturing of a mold for blowing PET bottles: features, terms, price

Features of production

The mold is a three-dimensional billet for the manufacture of PET containers using the blow molding method. Self-development of such blanks is a laborious and expensive process. In addition, to create such a production line, an experienced staff and modern equipment are required, without which a high percentage of defects is inevitable.

Molds for blowing PET bottles have found their application in various sectors of the national economy: food, chemical, pharmaceutical, construction, etc. Mold making is about creating a container with a unique design that provides brand awareness.

In addition to bottle molds, we carry out a full cycle of creating glass and plastic products. By ordering from KLONA , you are sure that the products are unique, reliable and take into account your wishes.

What the customer should know about

In order to achieve a result and not become a victim of misunderstandings with an industrial designer, we recommend that you adhere to the following tips:

1. Your result is directly proportional to the invested funds. It is not cheap to create an interesting corporate identity with a well-thought-out design of PET containers. Keep in mind that a professional approach to design includes market analysis, industry specifics and competitors’ style.

2. It is important for us to find out what kind of products you want to see. Experienced specialists work on the basis of the enterprise who will tell you what types of molds are suitable for your project and how much time you need to spend on testing and preliminary preparation for production.

3. Less is more. The simpler and more concise the future shape of the bottle, the fewer additional elements on it, the more advantageous it looks.

The process of creating molds for pet bottles goes through the following stages:

1. Statement of technical specifications. At this stage, the customer provides his vision of the future plastic product. As a sample, you can provide a finished bottle, a drawing or describe it yourself.
2. Product design. Preparation of design sketches of the form, creation of a drawing. More about press parts design read in our expert material …
3. Building a three-dimensional model of the product. The designer visualizes the model required by the customer. The design is carried out in a special program that allows you to examine the model in detail and make the appropriate adjustments. More details about 3D modeling read here …
4. Engineering analysis and volume calculation. Experts check whether the new form meets the requirements of GOST for disposal and transportation. It is possible to correct the model of the technical characteristics of the future bottle.
5. Designing a mold for PET bottles. Acceptance of the final form and volume, preparation for casting.
6. Development of programs for CNC machines. At this stage, the immediate preparation for the launch of production takes place.
7. Testing. Product tests are carried out on an injection molding machine. A series of closings are performed to identify irregularities or inaccuracies. After elimination of the shortcomings and revision, the company issues a guarantee for its products.

Industrial design and modeling studio KLONA helps the client to develop the mold of the bottle and takes into account his wishes at all stages of production. The results of our work are presented in portfolio … Order from KLONA and get a unique bottle mold tailored to your product.

What is the mold for PET bottles made of?

Molds are made of technical or food grade stainless steel, as well as duralumin. High-strength aluminum alloy D16T – most often used for the manufacture of molds for blowing bottles.

Advantages of using aluminum grade D16T:

1. Light weight. Because the mold is a removable part, the lighter it is, the easier it is to work with it.
2. The service life is over 5 years. For comparison, the average service life of a steel mold is 3 years.
3. The presence of anti-corrosion properties. The presence of the thinnest inert film on the metal surface protects it from oxidation.
4. Good machinability. Allows you to process material at high speeds and reduce the time required for machining.
5. High coefficient of thermal conductivity. The productivity of a mold largely depends on its ability to transfer heat and cool the plastic being processed.
6. Stability of the material. Minimal deformation during and after machining is guaranteed.
7. Subsequent surface treatment is possible. The creation of an oxide film on the metal surface will increase its wear resistance and strength.

Production time of the mold for plastic bottles

The time to manufacture a product differs according to the following criteria:

1. The complexity of the formation. The production of a standard form takes from 3 days. The creation of a unique product requires going through all the stages: from design to testing, so the term depends on the degree of complexity and is negotiated during the order or after agreement with the process engineer.
2. Used alloy. For example, it takes longer to produce an aluminum PET bottle mold than a steel one.

Blowing machine type. Creating a blank for a semi-automatic machine requires 7 calendar days, for an automatic machine – from 20.
