Baffle cavity blockage
Product Introduction:
①Injection molded type
Product structure: Support base (nylon) + foam (EVA foam)
Production process: Secondary injection molding or two-color injection molding
Scope of application: All bypass cavities
Product Advantage: Wide range of application, can be designed according to the shape of
sheet metal; can be designed as directional foam, good sealing stability.
②Extrusion type
Product structure: Foam adhesive (self-adhesive and adhesive type two)
Production process: Extrusion
Scope of application: Cavities with a maximum distance of less than 25mm from the cavity cross-section
Advantages: High degree of automation; simple process; foam can fill the entire cavity after foaming, sound-absorbing and sound insulation effect.
③Composite type
Product structure: Support mesh plate (stainless steel) + foam (EVA foam) + fixed clips (nylon)
Production process: Extrusion + punching + assembly
Scope of application: Regular cross-section, or the width of the cross-section does not change much
Advantages: High degree of production automation; high production efficiency; after foaming styrofoam can fill the entire cavity, sound-absorbing and sound insulation effect is good.
Due to modeling, design and other drivers, the body sheet metal cavity will often appears narrow and sharp corner features, watertight, airtight greatly reduced. To address this, we collect the current distribution of sharp angle at the sharp corners of the body of each part of the mainstream project, the angle α is about 7 ° ~ 35 ° range, for this type of angle we carry out a special combination of design.
HC Watertight Baffle is a highly dense foam product specialized in solving the cavity structure of the sharp corners of the car body, our products can efficiently achieve blocking and sealing of the sharp corners in different locations, providing a perfect solution for customers' automobiles that are involved in wading and floating water.
④Watertight Baffle
Product structure: a variety of materials (base: nylon, rubber: EVA, sealant) combined together
Production process: Multi-color (three-color) injection molding, new technology integrated molding
Advantages: automated robot pickup, the whole automatic production, product quality, cycle more stable.
