In this on-demand episode we answer your questions on Injection Moulding with Marco Tonnarelli, an Application Engineer at Protolabs. See below for a list of questions answered in this session:

· Do you offer 2K moulding solutions?

· If the priority is external face and it has no draft, is there a solution for this?

· With glass filled parts where the cosmetic element is vital, how do you recommend getting a good finish?

· Weld lines, any advice? How do I avoid them?

· Do you have design guides for self-mating parts? You can access the white paper referred to here. 

· What inspection services do you offer for Injection Moulded parts?

· Can you give examples of the metal on methods you use and the drawbacks of each?

· Do you have any special advice for the design of symmetrical parts, for example, for a part in an aircraft drone?

· What tolerance can you typically hold?

· Your tolerances are too large for my application, can you reduce them?

· Why would I use an aluminium tool? Does it not break or wear more than steel?
