Is it safe to melt plastic together?
Tips. Wash plastic well before melting it. Residues from cleaning products can create harmful fumes. Never melt unseparated plastic, because different plastic types have different melting temperatures, meaning some plastic will burn before others are melted.
How do you melt two plastics together?
Hot plate welding joins two plastic parts by melting them against a precisely heated platen for a prescribed period of time. The platen is removed and the two parts are forced together. The resulting joint bond is strong, permanent, and often hermetic.

Will plastic melt in boiling water?
Most plastic will not melt in boiling water. The melting point of a common plastic PET (plastic drink bottles) is 260°C. You would find it hard to find a plastic that will melt at 100°C. Some plastics however will become flexible and this temperature so you will be able to mold it into a different shape.
Is melted plastic oven toxic?
The short answer is probably not. While the jury is still out on this one, some organizations do point out the potential dangers of fumes from burning plastics. The USDA points out that any food permeated by any toxic fumes should be thrown out.
