Creating production injection moulds in a facility without a tool shop is a huge challenge. Managing a company department that must simultaneously secure ongoing production and create new moulds may generate delays and many other unforeseeable events. Ultimately, however, the development of our company in this direction is proving to be very beneficial, as it gives us unlimited control over the whole process – from the idea to the finished product. So how do we use this competitive advantage at Politech?
Injection moulding is one of the techniques of moulding plastics. This method is used to manufacture a range of shipping containers, packaging for industry, cosmetic products, household chemicals, as well as different types of closures, for example for PET bottles or perfumes. Why is injection moulding a good method for creating product packaging?
What does injection moulding consist of?
Injection moulding makes creating plastic packaging for various uses and in different forms possible. The injection method can be used to create containers and lids for foodstuffs, interestingly designed packaging for body care, and even packaging for household chemicals and goods.
Injection moulding consists in injecting plasticised material into an injection mould where it then solidifies. The plastics used in this process are in the form of granules. However, there are also other forms of processing for this material, which use prepolymers and agents that polymerise in the course of the moulding process. This method of injection moulding is called reaction injection moulding (RIM).
Injection moulders are essential in creating plastic packaging. They can be used for moulding thermoplastic and thermosetting materials.
Injection moulded plastic packaging – manufacturing process
The first stage in the process of moulding plastic packaging with injection is heating and melting the material. It is dosed from a container by means of a specially designed screw revolving inside a cylinder, which is then heated by the heating elements. The temperature of the plastic increases as a result of friction on the cylinder walls. Owing to the rotational motion, the heat is evenly distributed around the cylinder and the high pressure within the screw fosters the plastic to form.
The next stage in manufacturing injection moulded plastic packaging is the actual injection. The screw here moves in a rotational motion, but also in a reciprocating motion, which results in the molten plastic flowing over into the prepared injection mould. The injection mould is most often made of steel and its design allows it to become filled quickly, which favours effectiveness in the process of manufacturing packaging.
Depending on the type of plastic used to manufacture the packaging, it is cooled or heated once it is poured into the form. Thermosetting plastics require heating and the thermoplastic ones require cooling. With the use of an appropriate method of stabilisation for the plastic, it maintains the shape of the mould when it cools down.
Then the mould is emptied by means of automatic ejection. Ready packaging is cleaned of plastic residues, which may solidified in the feeding channels or on the parts connecting the two halves of the mould. This is conducted by mechanically cutting unnecessary elements, as well as by means of polishing the packaging.
Packaging we can manufacture by means of injection moulding includes:
- plastic shipping containers,
- industrial packaging (paint or foodstuff buckets),
- thin-walled injection packaging (containers for ice cream, margarine, cups for milk products),
- injection moulded boxes and jars for packing cosmetic and pharmaceutical products, as well as household chemicals.
The technology of injection moulding also allows us to create closures for different types of packaging.
PET bottles – injection blow moulding
We can also use the injection moulding technology to manufacture PET bottles. They are moulded by means of two methods. The single-stage ISBM is also referred to as injection blow moulding. The single-stage method makes it possible to conduct the production process in a single machine, resulting in a much faster and more efficient process. The clear advantage of this method is higher visual quality of the product in comparison to other methods. Through this method, packaging in non-standard shapes (oval, decentralised) can be produced, which are often used for example in the cosmetic industry.
Stress, putting our professional life before private matters, constant haste in all daily activities, eating on-the-go, a lack of sleep, no time for our family… These things are typical of contemporary times. And it is precisely them that the increasingly popular Slow Life lifestyle is supposed to counteract. Its characteristics are becoming noticeable in many areas of life as well as in various industries. Similar trends can be observed in the cosmetics market, where both the producers and the consumers are heading towards Slow Life.
The belief that in the past people did not dream about having luxury goods and products made by “known brands” is certainly mistaken. The wealthy often boasted about having fabrics imported from India, perfumes from France, or suits sewn by the best tailors. All kinds of such luxuries were, however, reserved only for the richest social groups.
Bespoke production is beneficial for the customer
Politech offers standardised products such as caps for perfume bottles, rings and jars for cosmetics. Every item and even individual parts of the items may be ornamented using the following methods: vacuum metal coating, UV varnishing, hot-stamping or full body colouring. Other options available: matt finish, glitter or pearl effect. That way, the range of possibilities is really huge and if we sold stock products, it would hamper the imagination of our customers and limit our development.
Shopping for the right perfume
Perfumes perfectly complement our personality and look, make us more courageous and catch the attention of those around us. They give us that special something that makes us stand out, that sets us apart. Good perfume is pricey, and if we want to spend a specific amount on it we should make a choice that we will not regret and that will have a positive effect on how we are perceived by others.
Trends in different sectors of trade and life in the 21st century are changing ever more rapidly, leaving consumers trying to keep up. Of course, those companies that move with the times and quickly adjust their products to trendy colours, patterns, textures, scents, and most importantly, consumer behaviours, expectations and experiences, benefit from doing so.
The appearance of any packaging plays a key role in the shopping process for the customer. What is more, consumer decisions are made in several dozen seconds, with only a few being spent on looking at a single product. The process of ensuring that our goods are the ones that attract the eye of the customer for longer begin with the development of the packaging.
According to one of the most important rules of marketing, a seller should not offer their clients a product, or rather a feeling, experience or dream which the product can accomplish. This rule is well known to perfume manufacturers who certainly do not offer water that smells like orange and ginger but “an oriental and tropical sensation that every strong man who wants to keep it natural needs.”
It might seem that product packaging always corresponds to the value of the commodity. In reality, however, form often alludes to the taste, smell or composition of the product or to abstract values rather than to the actual quality of the content. How to properly select the packaging for a product so as not to let down the expectations of consumers?
Although Slow Life continues to be one of the most influential trends in the consumer market, there is also a large group of people who have a different approach to life. This group of consumers chooses cosmetics with great care, assessing their composition. They also have certain requirements related to life in a constant hurry. Instant Beauty expects quick results, 3-in-1 cosmetics, and products combining care cosmetics with colour cosmetics.
Sophistication, sensuality, luxury, beautiful scents and chic. Why is it that France is associated with these values? Why is it that French perfume is also associated with these qualities? Is it because of the unique plants and climate, which influences the locally-grown perfume ingredients? Perhaps it is so because the French have the best “noses” in the world? Perhaps there used to be real reasons for this, but the advantage of French perfume today only extends to marketing?
The future of online cosmetic sales
The cosmetic market is one of the fastest growing industries in the world. The pace of growth is set by Asia, generating up to 35% sales in this market segment. Global cosmetic sales have been increasing by 6–7% annually thanks to the rising level of hygiene standards and growing consumer awareness, accompanied by increased distribution.
The history of perfume involves more than stories about ancient incense and associated rituals, or the most well-known fashion brands and French manufacturers from Grasse, where tons of flower petals and herbs were transformed into perfume. Unfortunately, it is also a story of filth, stench and very strong aromatic oils, the purpose of the latter being to mask the other, less pleasant smells.
How to reach your target group - Cosmetics for teenagers
Targeting, choosing the target group, and looking for a product niche refers to one particular issue. In order to really understand those terms, it is worth describing them using a specific example, such as cosmetics for teenagers. While creating a new cosmetic line, a company should accurately identify the recipients of their products and select the proper means of communicating with this group.
About creating glass packaging and our cooperation with Heinz-Glas Działdowo
After years of collaboration, relations between business partners begin to look routine. However, Politech is curious about the world and eagerly discusses issues related to cooperating companies. This is why we decided to conduct a short interview with Monika Kosmala-Sójka, Sales and Marketing Manager in HEINZ-GLAS Działdowo.
Perfumes are designed to captivate with their scent; however, we have known for a while now that we often judge them by their packaging, even before smelling them. Perfume brands have been trying to reach their clients by changing the visual forms of their perfumes, using different methods. Newspaper ads, billboards and TV commercials are just a part of it. Sometimes we may see perfumes in films. Is their presence on the silver screen accidental?
When creating a series for babies, cosmetics producers seem to have reached fertile ground. Parents willingly use protective products for their children in order to ensure proper development without any skin problems. Caretakers are, however, a more and more aware target group and their requirements of products are still growing. The question is, is it worth entering the market of cosmetics for babies?
The preferences of consumers change as quickly as anything in the world around us. Consumer trends can no longer be divided into decades but rather single years, and, in certain industries, even by season. So it is no wonder that companies that are trying to keep up choose rebranding, or at least the gradual revival of their packaging design.
Some substances require a little more attention than others. The reasons are varied. Sometimes a specific temperature must be maintained, on other occasions greater container strength is needed. At other times, the shape must be specially adapted to the form of the material carried inside, while sometimes not only is product safety of concern, but also that of people in its vicinity – as is the case with hazardous agents.
