Custom air conditioning parts for assembly moulding

In addition, our company has established cooperative relationships with plastic raw material suppliers, printing manufacturers, etc. to ensure the supply of raw materials and printing quality. Through our rich experience and perfect supply chain, our company can provide customers with high-quality customized custom air conditioning parts for assembly moulding products to meet their specific needs. At the same time, we have 10 years of professional foreign trade service experience, understand the foreign trade process, and better serve our customers. For custom air conditioning parts for assembly moulding products, we can make corresponding plastic parts, which is mainly done through injection molds.

The core challenge of customizing air conditioner assembly parts (such as the casing, air deflector, grille, motor bracket, water collection tray, etc.) lies in meeting the requirements of stable operation in harsh environments with high temperature, high humidity, vibration and cold and hot cycles for a long time. This is far beyond ordinary plastic parts and requires a targeted engineering solution.

��️ key points: Responding to harsh environments and functional requirements

Material selection: Weather resistance and flame retardancy are the bottom lines

Air conditioning parts are constantly exposed to a humid and hot environment and involve electrical safety. The materials must meet the following requirements:

High heat resistance: The indoor unit parts need to withstand temperatures above 60℃ (such as near the motor or air outlet), while the outdoor unit parts need to endure even more extreme temperatures (usually requiring the material's heat distortion temperature HTI to be greater than 90℃, or even above 110℃). Common materials include reinforced PP (PP+GF), heat-resistant ABS, and PA (nylon). The outdoor unit casing is mostly made of weather-resistant PP to resist ultraviolet rays and climate aging.

Excellent flame retardancy: This is a mandatory safety standard. Especially for parts adjacent to electrical components, flame-retardant materials that meet UL94 V-0 or at least V-2 standards, such as flame-retardant ABS, flame-retardant PP or flame-retardant PC/ABS, must be used.

Low water absorption and dimensional stability: Air conditioning condensate water and high-humidity environments require materials with a low water absorption rate to prevent deformation and jamming of parts due to water absorption and expansion. Glass fiber reinforced materials stand out in this aspect.

Structural design: Anti-deformation, confidentiality sealing, noise control

Dealing with "thermal expansion and contraction" : When designing, a reasonable expansion gap must be reserved for plastic parts to prevent stress deformation or abnormal noise caused by temperature changes. For instance, the assembly holes for fixing screws are often designed to be elliptical rather than circular.

Ensure sealing and drainage: For components such as water collection trays and drainage pipe joints that involve condensate management, their structural design must ensure 100% no leakage. This usually requires precise curved surface fits and strict deformation control.

Vibration and noise suppression: When the air conditioner is in operation, the fan and compressor will generate vibration. The parts (especially the air guide plates, fan blades and motor brackets) need to be rigid enough, and at the same time, the scientific layout of the reinforcing ribs and the anti-resonance design should be adopted to avoid generating unpleasant noise.

Molds and processes: Ensuring precision and consistency

High-precision molds: To ensure long-term sealing and smooth assembly, the precision requirements for molds are extremely high. For instance, the shaft holes, gears and other structures of the air guide plate need to be processed by slow wire cutting to ensure precise dimensions and wear resistance.

Addressing material challenges: If glass fiber reinforced materials are used, they have poor fluidity and cause significant wear to the molds. The mold should be made of wear-resistant steel (such as S136), and the gate and runner should be specially designed to ensure uniform filling and minimize warping caused by uneven orientation of glass fibers.

Strict process control: Materials must be thoroughly dried. A stable high mold temperature is required during injection molding to reduce internal stress, which is crucial for minimizing deformation caused by stress release in the later stage.

Test verification: Simulate harsh usage for over ten years

Air conditioning parts must pass reliability tests far exceeding those of ordinary consumer electronics, including:

Long-term cold and hot cycle testing: Hundreds or even thousands of cycles are conducted in high and low temperature chambers (such as -15℃ to 60℃) to simulate seasonal changes and test material aging, structural cracking and assembly dimensional stability.

Weathering and aging test: The outdoor unit parts need to undergo ultraviolet (UV) aging and salt spray tests to verify their resistance to fading, powdering and corrosion.

Fatigue and durability testing: The air guide plate and the gears of the stepper motor need to undergo tens of thousands of reciprocating motion tests to ensure no wear or breakage.

Flame retardant test: Conduct strict hot wire or needle flame tests on relevant components.

�� How to work effectively with suppliers

Clarify the environment and performance grade: When communicating requirements, it is necessary to clearly state whether the parts are for indoor units, outdoor units, or specific high-temperature areas, and provide specific temperature, humidity, flame retardant grade and service life requirements (such as "Ensure 10 years of normal use"). This is more important than simply providing drawings.

Require suppliers to provide material solutions and test reports: Qualified suppliers should be able to recommend specific material grades (including supplier and physical property data), and present reliability test reports of similar parts that have been passed as proof of capability.

Invest in prototypes and testing: Before mold opening, it is strongly recommended to use materials consistent with mass production to create functional prototypes and conduct initial assembly and durability tests. After the mold is completed, the first batch of samples must be used for comprehensive verification tests rather than merely for appearance confirmation.

Select partners with industry experience: Give priority to injection molding manufacturers that have been supplying air conditioning Oems or first-level suppliers for a long time. They have a profound understanding of the standards, testing requirements and common failure modes in the air conditioning industry, and can provide valuable experience from material selection to design optimization
