Frequently Asked Questions

What is blow molding used for?

Blow molding is a manufacturing process used to produce hollow plastic parts, such as bottles, containers, tanks, and ducts. It is ideal for applications that require lightweight, thin-walled, and sealed hollow structures, especially for packaging and fluid transfer components.

Injection molding vs blow molding: which is cheaper?

It depends on your production volume. Blow molding has lower tooling cost, making it more cost-effective for small to medium production runs. Injection molding has higher initial tooling cost, but the unit cost drops significantly for large volume production, making it cheaper for long-term mass production.

Which process is better for my product?

It depends on your part type, volume and performance requirements. If you need hollow parts with low to medium volume, blow molding is usually the better choice. If you need high-precision solid complex parts with large volume, injection molding is more suitable. You can upload your drawing and we will help you analyze and choose the best process.

Do you support prototyping before mass production?

Yes, we support rapid prototyping service, which allows you to test the part design and performance before investing in mass production tooling. The prototyping lead time is usually 7-15 days, and we can provide functional prototypes for your validation.
