Place of Origin:Qingdao Shandong, China (Mainland)
Brand Name: Lanmon
Surface Treatment: Gel coat Or Paint
Technique:Hand Lay-up RTM SMC
Material:Fibreglass Reinforced Plastic
Process: Hand-lay up
In the hand lay-up process, the laminate structure, commonly a single continuous strand glass mat, a woven glass mat or an advanced composite mat is manually “hand-laid” in the mold. The catalyzed thermoset resin is introduced, and the materials are formed to fit the mold surface using a “roll-out” process, as well as a number of specialized laminating tools. Additional layers of reinforced mat can be added to key structural points to enhance rigidity and performance. The Hand lay-up process is most effective when molding complex surfaces, and is commonly used in the transportation, recreation, medical, and agricultural markets.
Light RTM, a closed mold process, utilizes coordinating molds comprised of a rigid “A-side” mold, the base, and a lightweight rigid “B-side” mold that fits inside or on top of the A-side mold. Prior to affixing the two molds together, a pre-sized, cut and formed continuous strand glass mat, woven glass mat or Carbon fiber reinforcement is dry-loaded into the base mold. Rather than use pressure, RTM Light uses a vacuum, which pulls the catalyzed resin through the mold cavity, saturating the fiberglass reinforcement to create a part with consistent thickness, a smooth B-side surface, and controlled fiber/resin ratios. Relative to other Closed Mold Processes, Light RTM offers lower tooling costs.
The SMC / BMC molding process is a method of putting a certain amount of SMC / BMC molding material into a metal counter-die and molding the product at a certain temperature and pressure. The SMC is widely used in transportation filed like interior parts of high speed rail, auto spare parts and construction fild. The SMC / BMC molding process has the following characteristics:
1 Short molding cycle, high production efficiency, suitable for mass production of products;
2 Molded products are cheap;
3 High degree of automation and mechanization can greatly reduce labor intensity;
4 The size of the molded product is accurate, the surface is smooth, the quality is stable, and the replaceability is good;
5 Most products can be formed at one time without post-processing.
Polish: Mould must be polished before production which will guarantee the good and solidified surface
Clean: Special detergent are used to get the dust away from the mould which will make no dark markings in the
gel coat surface.
Release agent: This will be brushed on the mould to make ejection easily.
2nd Fiberglass and resin:
Gel coat: The color of products is decided by the gel coat,with thickness of about 0.3-0.5mm. UV resistant can
Surface mat: This is to avoid the air bubble on the surface, and also make fiberglass mat invisible from the finished
Fiberglass mat: Normally we use 300g/m2 (0.6mm thickness) and 450g/m2 (0.9mm thickness). According to your
requests on the thickness and strength, we will calculate how many layers of fiberglass mat should be used.
3rdSolidify: The time required for solidifying depends on thickness and weather condition.Normally 24 hours for one
piece to solidify to avoid any deformation after demoulding.
Demould: After solidified, the product will be demoulded
Cut and trim: We will mark the trim line and hole positions on the mould,then trim according to the marks to
gaurantee the mounting dimensions
4th Adhesion: Professional mould and Temperature and worker
5th Surface treatment :
7th Package Solution:
Our principle: Safe and economical
We choose economical packaging on condition that there will be no damage during transportation.Shipping: We are very glad to get the freight cost information for you
as we have long term cooperated forwarder company.
