SMC Bathroom Basin Molds

The SMC (Sheet Molding Compound) bathroom basin mold is the core equipment for mass production of integrated bathroom products. Its design accuracy and manufacturing process directly determine the core performance, appearance texture and user experience of the basin. The following will provide a detailed analysis from four dimensions: core features of the mold, advantages of molding effect, professional anti-slip design and multi-scenario application, combined with technical characteristics:

 

I. Core Features of the Mold

The SMC bathroom basin mold, relying on professional structural design and high-quality material selection, has formed core technical advantages suitable for the characteristics of SMC materials, specifically manifested as:

 

1.Strong process adaptability: It adopts a customized compression molding structure, with the core consisting of an upper mold cavity, a lower mold core, and a mold foot assembly. By precisely controlling the gap between the core and the cavity, a sealed mold cavity is formed. At the same time, it is equipped with 4 to 8 evenly distributed vacuum air ports, along with peripheral sealing grooves and foam rubber strip sealing components, to achieve vacuum compression molding, ensuring that the SMC material fills evenly without bubbles. The mold has built-in heating channels that can stably control the mold temperature at 140-160℃ through steam, hot oil, or electric heating methods, ensuring the material is fully melted and cured. It is suitable for large-scale batch production, with an annual output capacity supporting more than 500,000 pieces of products.

 

2. High-quality materials and excellent precision: The main cavity body is made of high-quality tool steels such as S136 and 718H, which feature high strength, high wear resistance and corrosion resistance. After precise processing, the dimensional tolerance can be controlled within ±0.5mm, ensuring long-term stability of the mold's precision. The mold surface can be treated as required, including mirror polishing and etching. Among them, mirror treatment can directly endow the product with an A-level surface texture, eliminating the need for subsequent spraying processing and significantly improving production efficiency.

 

3. High structural integration: The mold is equipped with an internal ejector pin base plate, ejector pin plate, and ejector pin assembly, ensuring smooth demolding of the product and preventing surface scratches. It can also integrate drainage ports, edge arcs, and other functional structures in one piece, eliminating the need for secondary processing and further enhancing production efficiency. Some high-end molds can even integrate in-mold coating technology, allowing the application of functional coatings on the product surface to be completed simultaneously with the molding process, thereby strengthening the product's protective performance. https://www.jiutaimould.net/

 

 

II. Advantages in molding effect

Relying on precise molds and scientific molding processes, SMC bathroom basins exhibit multiple core performance advantages after molding:

 

1. Excellent surface quality: The vacuum-sealed compression molding process eliminates formation defects such as bubbles and material shortage from the root. The product surface is high-gloss and flawless with uniform luster. The bottom basin formed by the mirror mold has an excellent surface finish, reaching the B1-level hydrophobicity standard. Daily cleaning only requires water and a soft cloth to remove over 95% of the stains, making maintenance extremely convenient.

 

2. Reliable structural strength and leak-proof: The integrated molding process eliminates the gap risks of traditional spliced bottom basins, fundamentally solving the leakage problem; meanwhile, the fiber-reinforced property of SMC material makes the bottom basin's impact resistance strength ≥ 12KJ/m², with excellent heat resistance, maintaining stable performance in alternating cold and hot environments, and having a service life of over 20 years.

 

3. Environmentally friendly, lightweight and efficient to install: The molding process emits no pollutants. The product uses a formaldehyde-free SMC resin formula, with a formaldehyde release of ≤ 0.01mg/m³, far exceeding national standards. The product weighs only 1/3 of a traditional ceramic basin (about 8kg), making it easy to transport and handle. Paired with a quick-install bracket, it can be installed in 15 minutes per unit, meeting the demands of fast-paced decoration.

 

4. Strong adaptability to irregular shapes: The molds can be customized to create arc-shaped, polygonal and other irregular-shaped cavities according to the layout requirements of the bathroom space. Relying on precise cavity design, the irregular-shaped basins can be formed in one piece. After forming, the basin body has smooth lines, a stable structure, and no seams, perfectly meeting the decoration requirements of irregular bathroom spaces.

 

 

III. Professional Anti-slip Design

In response to the core safety hazard of wet and slippery bathrooms, the SMC bathroom basin molds have built a comprehensive anti-slip guarantee system through refined structural design. The core technical parameters of each link are shown in the following table, and the specific design description is as follows:

 

Anti-slip design type	Core technical parameters	performance objective
Anti-slip texture integrated molding (convex and concave particle type)	Particle diameter: 2-3mm; Peak height: 0.8-1.2mm; Adjacent particle spacing: 5-8mm	Dry friction coefficient ≥ 0.75, wet friction coefficient ≥ 0.6. Balances both slip prevention and easy cleaning.
Integrated anti-slip texture molding (strip-shaped anti-slip grooves)	The slot width is 3-5mm, the slot depth is 1.0-1.5mm, the slot spacing is 8-12mm, and the slot direction forms a 30° angle with the drainage direction.	Dry friction coefficient ≥ 0.75, wet friction coefficient ≥ 0.6. Helps drain accumulated water.
Scientific drainage slope design	The slope of the edge area is 3°, the slope of the area close to the drainage outlet is 4-5°, the diameter of the drainage outlet is ≥ 50mm, and the bevel angle of the drainage outlet is 5×45°.	The surface water in the tank should be drained completely within 10 seconds, with the remaining water volume not exceeding 5 ml per square decimeter, and there should be no drainage dead zones.
Security detail optimization	Edge arc radius R5-R8, edge thickness 8-12mm; antibacterial coating thickness 0.15-0.2mm	Avoid collision injuries; Antibacterial rate ≥ 99.9%, Coating adhesion ≥ 4B grade (in accordance with GB/T 9286 standard)

 

1.Anti-slip texture integrated molding: The mold core surface is pre-processed with two customized textures, namely concave and convex particles or strip-shaped anti-slip grooves. After the product is formed, the surface directly has an anti-slip structure, eliminating the need for additional anti-slip pads. The anti-slip effect is long-lasting and not prone to wear. The texture parameters are optimized through ergonomic and anti-slip performance tests, ensuring core anti-slip performance while avoiding excessive gaps in the texture that could lead to dirt accumulation. During cleaning, water can directly flush away residue in the gaps.

 

2. Scientific drainage slope design: The mold cavity is preset with differentiated slopes following the principle of "converging towards the drainage outlet from the center", combined with a large-diameter integrated drainage outlet and a dedicated chamfer structure. This enables rapid drainage of accumulated water, significantly reducing the risk of wetness and slip caused by water residue. At the same time, it prevents the accumulation of sewage and the breeding of bacteria, enhancing the hygiene and cleanliness of the bathroom space.

 

3. Safety Detail Optimization: For special usage scenarios, large-radius arc edges are designed to avoid sharp corners and edges from causing collision injuries. Through in-mold coating technology, an antibacterial and anti-slip composite treatment is achieved, using a nano-silver antibacterial agent formula. This not only ensures anti-slip performance but also significantly enhances hygiene safety levels and product lifespan.

Its lightweight and quick installation features are particularly suitable for the efficient decoration needs of prefabricated houses.

 

2. Public service venues: It is suitable for high-frequency usage scenarios such as university student dormitories and rental communities. Its easy-to-clean, wear-resistant and long-lasting features can significantly reduce operation and maintenance costs. For hotels and homestays, customized textures and sizes can be used to match different decoration styles of bathroom spaces, enhancing the accommodation experience.

 

3. Special Function Scenarios: In places with extremely high hygiene and safety requirements such as hospital wards and elderly care institutions, the antibacterial and anti-slip bottom basin can meet the core demands of frequent disinfection, infection prevention, and collision protection. For industrial plant bathrooms, products with chemical corrosion-resistant formulas can be selected, which can withstand acid and alkali solutions with pH values ranging from 2 to 12, effectively dealing with oil stains and chemical reagent contamination.
