Ans: Yes, cold press juicers are made primarily by using stainless steel. Stainless steel makes the juicer and its parts sturdy and long-lasting. This makes the parts incredibly powerful allowing cold press juicers to handle large volumes of fruits and vegetables like ginger, sweet potato, etc. which are hard to crush. However, cold press juicers also have some plastic parts. These are made from plastic that is BPA free, non-hazardous, and safe to use.
