COVID-19 IMPACT

"Vacuum Impregnating Equipment Industry Had a Negative Effect Due to Reduced Capital Expenditures during COVID-19 Pandemic"

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

This has been due to several factors such as lockdown, shortage of labor and restrictions to industrial activities that affected demand from car manufacturers, aerospace and electronics industries among others. Those industries using vacuum impregnation in improving the performance of the components faced disruptions of production and decreased capital investments during the pandemic. Also, uncertainties in project schedules, especially those related to export controls in international trade, made procurement of raw material and vacuum impregnating equipment components for manufacturing more challenging.

Thus vacuum impregnating equipment was finding new application, as organizations refreshing their production lines and starting to bring industries back in line after the break. As a result, manufacturers set their sights on automation and remote monitoring, which became more popular when the pandemic started curtailing human interaction. Another interesting outcome was that continuing supply chain strength and product sourcing diversification also rose to the surface of awareness as important values.

LATEST TREND

"Integration of IoT and Industry 4.0 to Drive Market Growth"

There have been notable developments in the market which has the potential to boost the vacuum impregnating equipment market share. Present day systems are furnished with sophisticated sensors, real time control and data analysis tools through which manufacturers can improve the process of impregnation scrutiny and achieve improved efficiency. These systems put the operators in a position to be able to monitor significant parameters including the vacuum levels, temperatures and cycle time and also offer the maintenance alerts to reduce down times.

VACUUM IMPREGNATIONG EQUIPMENT MARKET SEGMENTATION

By Type

Based on Type, the global market can be categorized into Wet and Dry.

• Wet: A method of vacuum injection is the wet vacuum impregnation where the component is submerged into the liquid sealant under vacuum. It evacuates air from pores, thus giving the sealant a chance to bond firmly with the surface it is applying on.

• Dry: Dry vacuum impregnation firstly puts the component in vacuum so it removes all the air into the pores and then injects the liquid sealant material. It also makes sure that the sealant penetrates the holes left as a result of the vacuum created first. This process reduces scrap and is generally favored for use in applications where such components are needed for critical or high-accuracy uses.

By Application

Based on application, the global market can be categorized into Motor and Generator, Electrical Components, Metal Processing, and Others.

• Motor and Generator: In motors and generators vacuum impregnation helps to provide protection to the insulation of the windings or cores by applying resin or varnish. This enhances thermal conductivity performance, resistance to moisture and improves the structure’s resistance to wear and tear. It is essential for dependable performance when working under stressful condition.

• Electrical Components: Electrical parts, specifically the transformers, capacitors and coils are in most cases treated with vacuum impregnation for the purpose of providing insulation as well as discouraging short circuit connections. The process involves filling micro voids to further enhance the withstand capability of the material to moisture, heat and electrical failure thereby enhancing the reliability.

• Metal Processing: In metal processing, Vacuum impregnation averts leakage of fluids or gases on castings or even sintered metals which has small pores that he impregnates. This improves the mechanical properties and usability of constituents applied in auto, flying, and Industrial industry.

MARKET DYNAMICS

Restraining Factor

"Maintenance and Operational Complexity to Potentially Impede Market Growth"

These systems demand competent staff to administer and there will always be instances where due to system breakdown, production time is greatly affected. Infrastructure cost of acquiring and getting vacuum impregnating equipment is relatively high and thus prevent SMEs from taking up the technology. Other sealing methods that can be competitive with vacuum impregnation include treatment processes like powder coating or even electroplating may prove cheaper or even easier to implement for some applications.

Opportunity

"Expansion in Electric Vehicles (EVs) Markets to Create Opportunity for the Product in the Market"

EV motors and battery parts need high-performance sealing needs to deliver high quality, durability, and safety. Vacuum impregnation improves the insulation and thermal characteristics of motor windings and excludes leakage in important parts such as battery casings. With environmental changes and regulatory policies extending support to electric vehicles across the world, the number of evolutions in vacuum impregnation systems for EV requirements has emerged numerous opportunities to grow in the market.

Challenge

"Balancing Cost with Technological Advancements Could Be a Potential Challenge for Consumers"

While established multinationals are still willing to invest in such high-end systems, value added resellers, small and medium enterprises (SMEs) are constrained by high levels of capital investment. Furthermore, the creation of skilled labor to manage these complex computerized systems increase operation costs. Unfortunately, the low-cost delivery of these innovations is a significant barrier that manufacturers need to overcome with the assistance of cost-effective training solutions that should reach different industries.
