In today's world, housing has become one of the hottest topics, and once a house is under construction, home improvement becomes the main focus. Among all the elements of interior design, the door often acts as the final touch, playing an essential role in both aesthetics and functionality. So, what makes a good door? The answer lies in natural materials, and among them, solid wood doors are considered the top choice. However, many people wonder why solid wood doors are so expensive when they're just made of wood. Let's explore this topic and understand why solid wood doors come with a premium price.
(1) Natural Beauty: Solid wood doors are loved for their ability to bring a sense of nature into your home. With the rise of synthetic materials, natural resources have become more scarce. At the same time, growing awareness of environmental protection and health has led people to prefer natural materials. This trend has made the natural appeal of solid wood doors highly valued by consumers.
(2) Luxury and Craftsmanship: Solid wood doors are typically crafted from high-quality, rare tree species. These woods not only offer superior texture and visual appeal but also reflect a level of craftsmanship that sets them apart. As people's standards for quality and style continue to rise, manufacturers now use more expensive wood types such as European oak or ash. The intricate work involved in creating these doors adds to their overall value and beauty.
(3) Labor-Intensive Production: Unlike mass-produced alternatives, solid wood doors are often handmade, which significantly increases labor costs. The process requires skilled artisans who pay close attention to detail, ensuring each door meets high-quality standards. Additionally, the natural imperfections in wood limit material efficiency, making it even more costly to produce these doors.
Because of these factors—rare wood sources, high production costs, and limited availability—solid wood doors remain expensive. The price varies depending on the type of wood used, with rarer species commanding even higher prices. If you're looking for authentic, high-quality doors that combine beauty, durability, and sustainability, solid wood doors are definitely worth considering.

Diesel Engine
Diesel engine is an engine that burns diesel fuel to obtain energy release. The working process of a diesel engine is actually the same as that of a gasoline engine, and each working cycle also goes through four strokes: air intake, compression, work and exhaust.
The diesel engine sucks pure air in the intake stroke. When the compression stroke is nearing the end, the diesel fuel is increased to more than 10MPa by the fuel injection pump, and is injected into the cylinder through the fuel injector, and mixed with the compressed high-temperature air in a very short time to form a combustible mixture. Due to the high compression ratio of the diesel engine (generally 16-22), the air pressure in the cylinder can reach 3.5-4.5MPa at the end of compression, and the temperature is as high as 750-1000K (while the mixture pressure of the gasoline engine at this time will be 0.6-1.2MPa, and the temperature will reach 600-700K), which greatly exceeds the autoignition temperature of diesel. Therefore, after the diesel fuel is injected into the cylinder, it mixes with the air in a very short time and immediately ignites and burns on its own. The air pressure in the cylinder rises sharply to 6-9MPa, and the temperature also rises to 2000-2500K. Driven by high-pressure gas, the piston moves downward and drives the crankshaft to rotate to do work, and the exhaust gas is also discharged into the atmosphere through the exhaust pipe.
