Description
Technical field
The present invention relates to the overmolded field of section bar, the complete overmolded device of more particularly to a kind of discontinuous section bar and side
Method.
Background technology
In recent years, the development of plastic co-extrusion forming technique is very ripe, such as laminated plastics tubing, plural layers, many
Laminate material coextrusion mold technology etc., in addition, the technology of continuous section bar enhancing or cladding is also ripe already, such as PAP into
Type, coating technology of electric wire etc..Although these technologies have many differences, these co-extrusions or overmolded technology have
One common ground：Various ingredients, reinforcing material or the cladding section bar of composite are all continuous production or carried out with continuous morphology
Production, such as multi-component plastic melt, aluminium strip, metal filament.Therefore, these shaped devices are general all need to only enter to product
Row traction can be produced normally, but for discontinuous section bar, such as hollow or solid wood section bar, wood materials regenerative
The section bar reinforced plastics composites such as material, Wood-plastic profiles, metal rod sheet material realize outer cladding, discontinuous due to section bar,
It can not merely be produced by traction.In addition, some quantity-produced section bars, such as Wood-plastic profiles product, make according to practice of construction
With the section bar for requiring to intercept certain length, but during use, section often turns into the weak link of product, causes product to be inhaled
Water, mouldy, corrosion.
The content of the invention
