The invention relates to the melting of a thermoplastic, in particular for welding plastic parts (1). The plastic is heated by supplying an exhaust gas. According to the invention, a further gas is mixed with the exhaust gas prior to the supplying process.
Claims17
In a method of melting a thermoplastic for welding plastic parts where the plastic is heated with exhaust gas, the improvement comprising the step of:
- adding a supplementary gas to the exhaust gas before impinging the parts with the heated exhaust gas.
An apparatus for melting a thermoplastic for welding plastic parts, the apparatus comprising:
- a manifold that has output ports for discharging a hot gas for the purpose of heating the plastic of the parts, and
- a burner for generating exhaust gas in the form of process gas to melt the plastic of the parts and provided in a burner unit that has a separate housing and that is connected to the manifold by a hot-gas conduit,
- at least one additional supply line connected to the manifold for supplying thereto a supplementary gas that is added to the exhaust gas.
The apparatus according to 6, wherein the outer shape of the manifold is at least partially matched in shape by an outflow attachment to the shape of the plastic parts to be heated.
