Tin plated steel arrives in coils from the steelworks. Each one is about 4km long and a metre wide.

A colour printing press prints the can graphics directly onto the steel sheet before the sheet is slit and chopped to smaller sheets for bending into the can cylinders.

Welding the seam

The aerosol can welding process. Two copper electrodes roll alond the seen. A large electric current passes between the elctrodes and melts the two peices of steel together.

Welding the sheet edges together using electric current. Two electrodes press against the steel, one from outside and one from inside. The electrodes are connected to a power supply that drives a huge current of up to 5000 Amps through the metal. This melts the two overlapping layers together. This is called resistive welding. The current is pulsed at high frequency, one pulse for each spot or 'nugget' on the weld. To make a long seam the electrodes need to be wheels to roll along the can.

Making the perfect electrode wheel

For a perfect leak-proof welded seam the electrode wheels must also be perfect. After only one turn a copper wheel would pick up blobs of molten metal and be useless. The solution is to run copper wire round the wheels that is never re-used. The copper is recycled and made into new wire so the cost is reduced. 

The copper wire always presents  perfect new electrode surfaces as it is only used once. Getting the inner wheel into the inside of the can is not so easy as the can is moving in one direction. The trick is to curl the can into a cylinder just before it gets to the wheels.

There is a "nugget" for each pulse of current. The nuggets must just overlap. The slightest gap would cause a leak. Engineers regularly inspect the welds with a microscope.

A aerosol tin can approaches the wheels from the left. It has just been curved around the inner wire.

Hiding the seam

The seam on aerosol tin cans is a problem for can designers. The aerosol can is printed when it is flat sheet and then bent and welded. As ink is an insulator it must not cover the seam because it will stop the welding current from flowing though the tinplate sheet metal. This leaves an unprintable stripe on the can.

Engineers have managed to reduce the width of the stripe from 5mm to 1.5mm. Now that you have seen how the seam is made you can see that this is a big precision engineering achievement.

The final process is to add the aerosol can top (cone) and bottom (dome)

 

Choosing the right size and capacity for a hand care tube depends on several factors, including the intended use, product type, and customer preferences. Here are some considerations to help you make the decision:

 

Product Usage: Consider the application and frequency of use for your hand care product. If it is a daily hand cream or lotion used multiple times a day, a smaller-sized tube may be more convenient for on-the-go and frequent use. However, if it's a specialty treatment or mask that is used less frequently, a larger-sized tube may be more suitable.

 

Portability: Think about the portability and convenience of the hand care tube. If it's meant to be carried in a purse or bag, a compact and travel-friendly size may be preferred. On the other hand, if it's primarily used at home or in a professional setting, a larger-sized tube may be more appropriate.

 

Customer Preferences: Consider the preferences of your target customers. Conduct market research or gather feedback to understand their preferences regarding tube size and capacity. Some customers may prefer smaller sizes for trial or travel purposes, while others may prefer larger sizes for value and long-term use.

 

Product Consistency: Take into account the consistency and texture of your hand care product. Thicker creams or treatments may require a larger tube capacity to accommodate the product and allow for easy dispensing, while lighter lotions or gels may work well in smaller tubes.

 

Branding and Packaging: Consider your branding and packaging strategy. The size and capacity of the hand care tube should align with your overall brand image and product positioning. Ensure that the tube size allows sufficient space for labeling, branding, and product information.

 

Ultimately, it's important to balance the practicality, customer preferences, and product requirements when choosing the size and capacity for a hand care tube. Conducting market research and collecting feedback from potential customers can provide valuable insights to inform your decision.

Eye cream Tube with a metal applicator offers several benefits:

 

Cooling and soothing effect: The metal applicator, often made of materials like stainless steel or titanium, provides a cool and soothing sensation when applied to the delicate skin around the eyes. This can help reduce puffiness, soothe tired eyes, and provide a refreshing feeling.

 

Enhanced product absorption: The metal applicator helps to gently massage the eye cream into the skin, promoting better absorption of the product. The massaging action can stimulate blood circulation, allowing the active ingredients in the eye cream to penetrate more effectively and deliver their benefits.

 

Depuffing and tightening effect: The cooling effect of the metal applicator can help reduce under-eye puffiness and minimize the appearance of dark circles. The gentle massaging motion can also promote lymphatic drainage, reducing fluid retention and giving the eyes a more tightened and lifted appearance.

 

Precision and targeted application: The metal applicator typically has a smooth and precise tip, allowing for targeted application of the eye cream. This ensures that the product is applied exactly where it is needed, such as fine lines, crow's feet, or under-eye bags.

 

Hygienic and easy to clean: Metal applicators are generally hygienic and easy to clean. They can be wiped clean with a soft cloth or sanitized with alcohol between uses, minimizing the risk of bacterial growth and maintaining good hygiene.
