Progressive molding of carbon steel
Progressive die stamping of hot-rolled and cold-rolled steel is a
die-based cutting and forming process that includes a series of
stamping stations. These stations simultaneously operate the steel
plate on the coiled strip. Progressive die ("Die") is a metal
processing equipment designed and manufactured to transform a flat
strip of metal raw material into a complete part that meets
printing specifications.
Metal stamping of various size parts
In Qingdao Yonglihao, we can produce high-precision, highly
detailed customized hot-rolled and cold-rolled precision metal
stamping parts and components that meet all customer design
specifications.
Using our production capacity of up to 440 tons of presses and our in-house precision stamping dies and tools, we can manufacture parts with a thickness of only 0.002 inches while maintaining tolerances that often exceed industry standards. We provide services to customers in all industries, and provide short- and medium-term metal stamping parts for parts and parts of various shapes and sizes.
Custom-made stamping tools and dies
Qingdao Yonglihao's stamping dies are custom tools that can be used
with stamping machines to cut or shape steel plates into desired
shapes. Most stamping tools are custom manufactured, usually made
of tool steel, which is sufficient to cut most other types of
metals while maintaining the tolerances required for stamping
parts.

Below is some questions you may want to know:
Questions: How to know the chemical composition of stainless steel
deep drawing parts according to our requirements?
Answers: When we offer samples or batch parts, we will also send you our
material list from our material factory, it shows more detailed.
Questions: How to guarantee your final size can meet our drawing
request?
Answers: we will make moulds according to your 3D drawing. And we also do
sampling when batch production start, to make assure the final
dimension can meet your request.
Questions: How to make sure the color after painting or powder
coating can be correct?
Answers: We have color card with different color number, such as RAL9016,
we will contrast the sample surface and color card, to make sure
the final surface effect is correct.
Questions: Generally, how do you packing the goods?
Answers: normally, for inner package: the goods is nude, for outer package:
carton + plywood. If you have special request for inner or outer
package, pls indicate it when you send us new inquiry.
Questions: If we find the defect products exist in the batch parts,
how to do?
Answers: Yes,your caution is very good, in fact, when batch production, we
need do sampling. Before shipment, we also do testing to make sure
the quality is ok. If you found several defect product exists, pls
take photos and send your quality feedback, we will check and send
you quality products. But pls be assured that our products is
qualified, unless caused by the worker's mistake to place.
