Frequently Asked Questions
What materials are recommended for high-gloss cosmetic mold inserts?
For high-gloss cosmetic applications, S136 / 420SS stainless steel (HRC48-52) is recommended. It offers excellent corrosion resistance, superior polishability (Ra < 0.4μm), and long mold life. For general purpose applications, H13/SKD61 is suitable.
What are toothed threaded shafts and where are they used in molds?
Toothed threaded shafts are drive components with precision-cut gear teeth or splines that transmit rotational motion in unscrewing mold systems. They are critical for bottle cap molds, enabling the unscrewing of caps from threaded cores.
What is the standard dimensional tolerance for your mold components?
We maintain a high precision dimensional tolerance of ±0.01mm, ensuring exact fits for high-cavitation and precision injection molds.
Do you offer custom surface treatments like Nitriding?
Yes, we provide Nitriding surface treatments to enhance wear resistance and durability, as well as mirror polishing for aesthetic parts.
Can these components be used for automotive mold applications?
Absolutely. Our precision core pins and inserts are suitable for both cosmetic packaging and technical automotive mold requirements.
What information is needed to provide a custom quote?
To provide an accurate quote, we typically require 2D or 3D drawings (STP, STEP, or IGS), material specifications, hardness requirements, and surface finish details.
