Why choose cast aluminum doors? Are they both cast aluminum doors but have obvious price differences?

Cast aluminum doors are an emerging high-end entry door in China. They are thick and elegant, durable, anti-theft and explosion-proof, corrosion-resistant and discoloration-resistant, and have been recognized and favored by customers.

They are also cast aluminum doors, but there is an obvious price gap?

Today I will take you to understand the reasons for the price difference between cast aluminum doors.

Reason 1 for the price gap: outer panel material and craftsmanship

Ordinary cast aluminum doors use aluminum ingots with lower standards or unreasonable proportions. Rust spots will appear after prolonged oxidation.

Using high-quality alloy aluminum ingots (aviation aluminum) with pure white color, no impurities, stable structure, strong performance, oxidation resistance, corrosion resistance, and good surface paint adhesion, and will not cause paint peeling problems.

The same is cast aluminum plate, but the process is different and the quality is also different. The traditional old-fashioned craft uses sand casting. The aluminum plate cast in this way has a lower density and slightly lower strength than the aluminum plate cast by vacuum precision casting.

Using a 100 kilowatt motor negative pressure system (vacuum casting line) to die-cast, the molecular structure of the aluminum panel is closer than that of ordinary hand sand molding.

Reason 2 for the price gap: inner panel material and process

General cast aluminum doors on the market mostly use inner panel materials Steel plate splicing or solid wood composite. The steel plate splicing inner panel is low-cost, but it is slightly inferior to the solid wood composite backing in terms of appearance, grade, and matching with the overall home style. The surface of the board is generally constructed with polyester chemical paint. The shape of this armored door is smooth and has no three-dimensional effect. The formaldehyde remaining in the surface of the polyester chemical paint is highly toxic and is not environmentally friendly.

The inner panel material is commonly used in North America and Africa. , Carbonized logs of precious tree species imported from Southeast Asia such as white wax, red oak, Burmese pomelo, ebony, cherry wood or fashionable environmentally friendly boards, with natural vegetable oil wiped on the surface – Wood wax oil, the texture is natural and noble, exuding a faint fragrance of logs, and the log panels are made of environmentally friendly, high-grade log materials that have been treated with a 200-degree long-term deep carbonization (heat-proof, moisture-proof, crack-proof, and deformation-proof) process, 3 degrees ( Steel core, panel, card edge) armor assembly structure, the product structure has stable performance and is not easy to deform and crack.

Three reasons for the door price gap: hinge material

Nowadays, cast aluminum doors mostly use ordinary steel six-dimensional adjustable hinges or heaven and earth hinges. In terms of material, ordinary steel hinges. Because it is stamped in a mold, this hinge is formed by forcibly stamping and deforming the metal material. The structure of the material itself has changed, so this hinge It is easy to sag, bend, deform, or even get stuck.

Using a patented product – high-pressure precision cast 304 stainless steel seven-dimensional hinge. Since the molecular structure of the hinge casting material itself has not undergone any changes, this The hinges have the characteristics of super load-bearing, no deformation, and no sagging. A single hinge can bear up to 400 kilograms.

Reason 4 for the door price gap: lock body and lock core

Ordinary armored doors generally use spring-driven lock bodies. The performance of the lock body of this structure is unstable and prone to mechanical failure. It adopts silent gear transmission lock, which is a seamless transmission. The mechanical structure operates smoothly and safely. Guaranteed.

Ordinary armored door lock cylinders generally use pinball structure lock cylinders or blade lock cylinders. They adopt imported three-dimensional structure lock cylinders, that is, pinball structure + blade structure + magnetic structure, which fully comply with EU safety level standards and technology. The opening may be infinitely close to 0.

Five reasons for door price gap: Sealing

The thickness of the door leaf is 90-95mm. It adopts the original beveling process of the door leaf. The door leaf opening and closing is more flexible. In particular, the door gap is smaller than that of ordinary armored doors, which reduces air circulation; the product is imported from the United Kingdom Q-LON imported special tape (main material is three Ethylene glycol, no odor, smooth and beautiful surface, resistant to oxidation and corrosion, high temperature resistance of 100°C, low temperature resistance of -45°C, no cracking, long service life, no aging and deterioration for fifty years) four-dimensional four-dimensional air-tight system; both It reduces the noise of closing the door and strictly isolates the indoor and outdoor areas from external noise. It achieves complete isolation of indoor and outdoor air due to the temperature difference between sound and outdoor environment; aviation aluminum foil is used as filling material in the steel core (aviation aluminum foil is known as the \”King of Insulation Materials\” and is a new generation of thermal insulation, fireproof and sound insulation materials) ;

The sound insulation performance of the product reaches It reaches the national level three standard (-33 decibels), and the thermal insulation performance reaches the national level six. It is a low-carbon and energy-saving product in the true sense;

Ordinary armored doors generally use solid wood edge sealing technology around the door leaf frame, and the edge sealing is easy Glue cracking, Di Zino uses super-hard space aluminum armorThe edges are collected, and then precisely locked and assembled with double rows of precision machine screws and the steel core of the door leaf.

Six reasons for door price gap: Armored inner core

The steel core of cast aluminum doors for ordinary doors generally uses ordinary galvanized sheets. The steel core for cast aluminum doors uses automotive-specific electrolytic plates. Automobile-specific electrolytic plates have super hardness, oxidation resistance, corrosion resistance, etc. Features.

Seven reasons for the door price gap: Paint surface

The metal paint surface material uses plastic powder primer produced by the world\’s top chemical coating manufacturer Akzo Company of the Netherlands. It is hand-painted with six degrees of color and fluorocarbon paint imported from Germany is used for gloss. It has great artistic beauty and environmentally friendly products. , Resistant to oxidation, anti-corrosion, anti-ultraviolet, strong adhesion to surface materials, and does not fade for 30 years.

In summary, the productThe quality gap and the proliferation of \”fake and shoddy\” products have resulted in a huge price gap! Responsible brand manufacturers prioritize the quality of their products, while irresponsible manufacturers prioritize making money.
