Electrostatic Painting: A Boost Towards Efficiency and Waste Reduction

Venatures — Mon, 27 May 2024 07:31:00 +0000

In this article, we discuss what electrostatic painting is and how it helps us bring our clients’ projects to life by optimizing waste reduction and increasing production quality.

What is Electrostatic Painting?

Electrostatic painting is an advanced technique used to apply paint on various surfaces, including furniture. During this process, the paint is sprayed through an electrostatically charged gun. The electrically charged paint particles are attracted to the wooden surface of the chair, which is oppositely charged. Consequently, this interaction creates a stronger and more uniform adhesion of the paint particles, ensuring a high-quality finish.

The Advantages of Electrostatic Painting

We have analyzed reports on our painting process and are proud to note that electrostatic painting is helping us improve this process fivefold because:

Reduced Paint Waste: Thanks to the electrostatic charge, the paint particles are more efficiently attracted to the chair’s surface, reducing waste by up to 30% compared to traditional techniques.
Uniform and Consistent Finish: This method ensures an even distribution of paint particles on the wooden product’s surface, eliminating streaks and blotches, and guaranteeing a flawless finish.
Time and Efficiency Savings: By not requiring multiple layers of application to achieve the desired finish, electrostatic painting is generally faster than traditional methods, allowing for increased production and greater efficiency. This translates to reduced processing times and operational costs.
Environmental Sustainability: When combined with the use of water-based paints, it helps reduce the overall environmental impact of the painting process. Water-based paints are less harmful to the environment compared to solvent-based ones.
Quality Control: This technique offers precise control over the amount of paint sprayed, ensuring greater consistency and quality in the furniture finish.

Why is there a 30% Savings?

From the same reports, we have noticed that traditional paints often cause greater material waste for various reasons:

No Controlled Dispersion: The paint particles are distributed less controlled, causing more waste.
Lack of Optimal Adhesion: The paint particles do not adhere evenly to the surface, increasing the risk of waste.
Multiple Layers Required: More layers may be necessary to achieve an even finish, increasing paint consumption.

The Economic Impact of This Method

Electrostatic painting not only offers quality and sustainability benefits but also has a positive economic impact. By reducing paint waste by up to 30%, this technique leads to significant production cost savings. Paint particles are more efficiently attracted to the chair’s surface, reducing overall material consumption and thus the costs associated with purchasing paint. Additionally, the faster process speed and reduced processing times further contribute to operational cost savings.

What We Can Learn from This Analysis

Electrostatic painting represents a significant innovation in the custom furniture manufacturing sector. With its numerous advantages, including waste reduction, a uniform and high-quality finish, increased efficiency, and environmental sustainability, this technique offers an excellent way to enhance the quality and sustainability of furniture production.

Towards a More Sustainable Future

Furthermore, we are committed to reducing waste and adopting sustainable practices. Following the principles of “zero waste,” we carefully analyze our production processes to identify and reduce all types of waste, helping to preserve the environment and ensure the sustainability of our operations.

What is the Kanban Method?

Venatures — Sun, 12 May 2024 06:52:04 +0000

What does Kanban mean? According to the literal translation of the Japanese term, Kan (看) means ‘visual’ and Ban (板) means ‘signal’. This Lean Production technique facilitates the Pull Flow of materials, based on physical cards that consent to the production, purchase or handling of materials.

Inspired by an American supermarket

Kanban originated in the Toyota plants in the 1950s as part of Lean Logistics. Thanks to this production model, industrial engineer Taiichi Ohno managed to pull Japanese industry out of the economic crisis it had fallen into after the Second World War. Ohno was inspired by the procurement methods used by American supermarkets. In the shops, customers take the labelled products from the shelves.

Once customers have gone through the checkout, shop staff record information about the stock status of the shop allowing them to issue an order to the warehouse, made possible because the warehouse and the shop share the same labelling system.

Once the supermarket’s shelves are replenished, the warehouse sends a supply order to the wholesalers or manufacturers, which is repeated throughout the supply chain, creating a cycle where the ultimate goal is to ensure that the shelves are stocked with products. In order to keep control of stock at all times and avoid the dreaded ‘empty shelf’, a reorder point must be set up. This is the idea behind the Kanban system.

How we apply the Kanban in our company

There are two main tools that enable us to use the Kanban method: coloured cards and blackboards. The coloured cards are used to request the raw materials needed for the production processes. Once the operation is complete, the card returns to its point of origin. The Kanban cards contain the information identifying the batches of material: ID, size, customer, location, etc. The cards are hung on the containers or shelves where the product was located.

The boards allow the cards to be placed in an organised manner. Each column shows the status of a task and the person responsible for carrying it out.

The Kanban system is self-regulating if the demand fluctuations are small enough, but if the fluctuations are larger, the number of cards must be reduced or increased.

The number of cards available for a given code has a direct influence on the amount of stock in the warehouse: the aim of the method is to reduce the number of cards to the minimum, in an effort to improve the process (production time, set-up, waiting, transport) and consequently lower the lead time. Our goal is to be faster, with less stock.

Kanban model vs MRP (business software)

For the Kanban system to work, it is absolutely essential that it is correctly dimensioned. In this way, the advantage, apart from its ease of use, is the optimisation of stocks on the basis of actual consumption, compared with the traditional use of MRP (the company software for ensuring the correct purchase of materials). In fact, it has been demonstrated that a correctly dimensioned Kanban system offers a lower stock level compared to the reordering logic calculated in the traditional MRP way.

What are the advantages of the Kanban method?

It visualises the work progress and controls each phase of the production and supply cycle.
It prevents the formation of bottlenecks.
It works as a control system for production and materials available in the logistics network.
It avoids overproduction and overstocking, allowing you to recover warehouse space.
It allows you to respond to customer demand with precision.
It is sustainable: it only takes from nature what is needed.

How much you can save with the Kanban method

The costs of warehousing can be quantified in capital assets (+ insurance costs), stock management (physical and accounting), space and the risk of obsolescence and deterioration.

In our experience, we have found that by using the Kanban method the savings on these costs is quantifiable at an average of 20%, and in some cases, we have managed reduce these costs to nil.

Can wood be transformed within 100 metres?

WHAT IS THE VALUE OF 100 METRES?

In this article we want to talk about a number that is particularly important for our production process. We are talking about 100 metres, which is the exact distance that wood travels within the company to become a chair.

We have gone from 29 km to 100 metres

Over the last few years, we have worked on rationalising and improving the efficiency of our production process. Our optimised production system, after each stage of the process was put in order, saves us many metres, which were nothing more than time lost back and forth in the warehouse. How did we achieve this? We completely revised the production layout and worked hard on optimising setup times. Out of curiosity, we measured the distance travelled in metres by the same parts before the reorganisation of the production process and calculated that previously it would take up to 30 km to make a chair. Today the distance is just 100 metres to make the same product.

The production system now

Today, the material ready for processing undergoes a pathway of transformation via the three main lines on which our production is organised and which are outlined on the floor of our company. On each of these three lines there is a sequence of machinery designed and grouped to ensure workflow and to always move in a single direction. In other words, the flow of the process never goes in reverse: the pieces of wood slide on special trolleys and only travel 100 metres before becoming a chair.

Other numbers that add up: warehouse space occupied and transportation

Apart from the 100 metres, there are other numbers that have been drastically reduced by optimising the production process. For example, the square metres of warehouse space occupied by the raw material: we have gone from occupying 1000 m² to 400 m². A huge saving of space. Transport costs are another aspect that have improved enormously and have been reduced by 70%. These many factors combined make us altogether faster in the production and delivery of orders.

What is the value of these 100 metres to the customer?

Let’s start with an important principle: anything that does not represent a value for the customer could be generically defined as waste. Therefore, all you need to do is to eliminate waste in the process to reduce the cost/price. The hardest thing to do is to recognise this waste. For us, it has been a long road towards this awareness. Along the way each element of the production process was observed to see whether it had a positive impact on benefits or costs. In this way we were able to understand which activities generated value or, on the contrary, waste. This study means now we can say that the 100 metres are a value for customers, because the resulting product for them (and this also applies to us as a company) is made with less waste and therefore a reduced cost.

If we could summarize this concept with an image, it would be this one:
