Oven melting encapsulization of hypodermic needles by syringes

The results of a study to determine the time and temperature conditions necessary to melt standard injection syringes are presented. The polypropylene syringes are melted to form a solid block of material encapsulating the attached stainless steel hypodermic needles, making them appropriate for further processing into other products. The desired result was obtained after two hours at 200 degrees C and can be replicated easily in a location such as a rural clinic in a developing nation.
