Custom Electric Popcorn Maker Parts CNC Machining for Consumer Goods Industry

In order to deliver high-end Custom Electric Popcorn Maker Parts CNC Machining for Consumer Goods Industry, we utilize our expertise in machining while still maintaining quality by utilizing multi-axis CNC machining centers, 5-axis simultaneous milling systems, and precision Swiss turning systems. All components, like the cylinders of 2-8 liter aluminum 3003 heating chambers, which have bottoms machined to ±0.012mm relative flatness, and the stirring paddles made of 304 stainless steel, which have balanced arms of grade G6.3 and polycarbonate steam venting lids with rigid ±0.5mm spacing, and the motor shrouds with super tight bearing seat ±0.010mm fit, and the kernel chutes which have tight ±0.015mm tolerances, are engineered to ensure maximum reliability in popcorn provision, maintaining food-safe standards for 2,000+ cycles_exports.

In our Costa Rica facility, we achieve the following capabilities: CNC (Computer Numerical Control) precision milling where we heat chamber bottom surfaces accomplish a flatness tolerance of +/-0.012 mm, while we do 5-axis machining for complex stirring paddle geometries (accomplishing arm dimensional accuracy: +/-0.015 mm). Then we do precise turning for motor drive shafts (-0.012 mm diameter tolerance) while with a concentricity of 0.010 mm. We perform precision axial drilling for steam vent holes (3-6mm diameter) with +/-0.015 mm diameter tolerances with a positional accuracy of 0.5mm, as well as, precision boring for bearing seats with total tolerances of +/-0.010 mm with tolerances of a surface finish of 0.6um. Then, we do threaded hole milling for the closing lids where we do M5-M8 pitch tolerances of +/-0.012 mm. We do other capabilities as well such as, dynamic balancing of up to g6.3 grade and thermal uniformity challenges in arrays.

We make parts for electric popcorn poppers and one of the products we work with is aluminum 3003 which has a thermal conductivity of 159 w/mk. This makes the heat chambers able to heat to a uniform temperature of 180-230 degrees Celsius. This aluminum is editable for drawings and is coated with PTFE which is 20-30 micrometers thick and FDA approved per 21 CFR 177.1550. We also use stainless steel 304 for the mixing paddles which is food approved and has FAD CFR 21 compliance. This stainless steel is also able to resist corrosion and has a dynamic balance. We use food grade polycarbonate for the transparent view lids that has a heat resistance of 135 degrees Celsius, impact resistance of 60 kj/m, and optical clarity of 88-90% so the user can view the popcorn that is popping. The collection bowls we make for the poppers is made of food grade polypropylene polyester that has heat resistance of 100 degrees Celsius, and impact resistance. Aluminum 6061-T6 is also used. This aluminum is used on the motor cookie on the outside of the popcorn popper, Anodized protection makes the aluminum last longer and food grade silicone gaskets with Shore A hardness 40-60 are used for sealing. The gaskets are able to withstand temperatures to -40 degrees Celsius to more than 200 degrees Celsius. Lastly, a ceramic coating is on the heating surface which makes it non stick and is more effective.

Efficient, consistent popping of kernels is vital to any popcorn maker's success, and we account for that by designing heating chambers that pop 95-98% of kernels at the full popping temperature of 200-220°C with a uniformity that yields a flat temperature gradient of less than 10°C at the heating surface, stirring paddles that smoothly operate at 40-80 RPM and quench the burning of kernels, and steam vents that balance moisture retention and heat retention for a popping duration of 3 to 5 minutes. We've designed our heating chambers and steam vents to withstand over 2000 popping cycles to ensure over 5 years of household use, and we've designed every part to meet FDA Food Contact, UL Appliances, and other safety standards.
