Solution Solution

The molding and processing methods of plastic products for household appliances mainly include injection molding, extrusion molding, thermal molding, hollow molding, laminated molding, compression molding, transfer molding, foam molding, pouring molding, inlay casting, sealing casting, etc., of which injection molding is the main method.

Some new plastic processing technologies and equipment have been widely applied in the molding of plastic products for household appliances, such as precision injection molding, rapid prototyping technology, melt injection molding technology, gas assisted/water assisted injection molding technology, electromagnetic dynamic injection molding technology, and film covered injection molding technology.

Appearance color module

Using bright, glossy, and scratch resistant materials

The material colors are more diverse, such as bright black, purple red, tender green, and bright red, Sea blue, etc.
Spray free series - Pearl/Metallic color

Can make plastic products achieve silver white, earthy gold, and silver gray without the need for spraying or electroplating The same effect as metal.
Other special effects - marble/crystal flow color

Make plastic products have the same color as marble or granite.

Safety material module

High flame retardant materials, halogen-free and low smoke materials

For example, internal or external components such as refrigerators, air conditioners, washing machine motor boxes, etc. use low smoke bromine phosphorus synergistic high flame retardant PP/ABS PS or low smoke halogen-free flame-retardant PP/ABS/PS/PBT materials, meeting the requirements of 1.5mm 5VA, GWIT850 ℃, etc.

01
High performance materials

Permanent anti-static colored PP/ABS/PS and other materials are used for refrigerators, air conditioners, and washing machine casings; High flame retardant and high leakage trace ABS/PP/PA/PBT and other applications in electronic control components; Conductive PP/ABS/PS/PBT and other materials are used for internal functional components. full Foot white permanent anti-static 109, high CTI value (600V) and other requirements.

Can be applied to refrigerators, air conditioners, washing machines, etc
Internal or external components

Non-toxic environmental protection material: Using low VOC volatile materials (PP/PS/ABS, etc.)
Applied to internal and external components of household appliances
Using plasticizer free elastomer material (TPE/TPV)
Applied to door seals and gaskets.

Environmentally friendly adsorption material: The internal and external components of household appliances can be made using
PM2.5 adsorbent material (such as Vishectone filling)
Formaldehyde adsorbent material (filled with activated silicon/alumina)
Negative ion releasing material

Low cost material module
Lightweight material module
Energy saving and low-carbon material module

New low-cost functional materials

Using inexpensive polyolefin materials, such as high gloss PP instead of ABS and ABS/PVC instead of flame-retardant ABS;

Functional components are replaced with plastic instead of steel, copper, glass, and aluminum, and mirror high glass fiber PPS is used instead of electroplated metal parts;

Environmentally friendly high-performance recycled plastics (PP/PS/ABS, etc.) replace new materials and comply with the EPEAT electronic product environmental impact assessment tool in the United States.

Under the condition of constant intensity, reduce the dosage

The internal components of household appliances are made of microporous foam structural materials (PP/ABS/PS, etc.);

Using 3D printing materials (FDM/SLA/SLS) for rapid sample preparation in household appliances, reducing research and development costs;

By optimizing product structure design through CAD/CAE, the design of internal and external components and products of household appliances can be optimized, reducing usage.

Industry chain integration: customized modified plastics for petrochemical manufacturers

Petrochemical manufacturers collaborate with modification companies to customize specific materials: high gloss ABS/PS/PP, transparent ABS/PS/PP, self flame retardant PA6/PA66, long-chain nylon, ASA.

Replacing glass with plastic, high transparency and rigidity materials

High transparency PP/ABS/PMMA/PETG/PES/PFF materials are used on observation windows and other components to meet food hygiene or scratch resistance/strength requirements while ensuring transparency.

Replacing steel with plastic, a material with high rigidity, strength, and dimensional stability

Using high-strength materials with high glass fiber content (>50%) and long glass fiber reinforced materials (LFT-PP/PA) for technical structural components such as refrigerators, air conditioners, washing machines, etc; Fiberglass reinforced special engineering materials (PPS/PEI) are applied to wear-resistant components. These materials meet the requirements of high strength, high wear resistance, water boiling resistance, and temperature resistance for structural components; In addition, microcellular foam materials can significantly reduce the weight of plastic used in household appliances at the same strength, without warping or shrinkage marks, and have higher strength and processability.

New low-carbon functional materials

Low carbon skills have become an inevitable trend in the development of home appliances, and biodegradable materials and their alloys (starch, PLA) can be used for home appliance packaging or non structural components; Natural fiber reinforced materials (PP) can be used to replace fiberglass reinforced materials; High heat and weather resistance, high rigidity polypropylene can be used instead of PS/ABS/PA, such as air conditioning PS skeleton. This is mainly due to the fact that polypropylene has the lowest carbon emission index (1.95) among household appliance modified plastics, and the trend of low-carbon development through the extensive use of polypropylene composite technology can reduce costs.

Energy saving and noise reducing functional materials

The sealing and shock-absorbing components of household appliances are made of thermoplastic elastomer materials (PVC/TPV/TPE, etc.);

The low-noise fan adopts microporous foam material (increasing coaxiality and improving dynamic balance);

The compressor shock pad is made of high damping shock-absorbing elastic material to reduce noise.
