Plastic Injection Molding Factory
In January 2008 ChinaForgeTM
founded Hangzhou Tanda
plastic injection molding shop in Hangzhou, China.
Our Hangzhou factory specializes in
manufacture of high-quality plastic parts and products, where
high-precision, high clarity, excellent surface finish, and cleanliness
We operate 100- and 161-metric tonne
molding presses (110- and 178-ton). Shot sizes can be up to 149 cc on
the former and
up to 259 cc on the latter. For more information about our
machines, please see the technical specifications.
We have customized our injection molding machines to
improve part quality beyond what most Chinese
molders can accomplish:
- All molding machines have high compression ratio screws
for higher precision engineering parts and higher clarity and surface
appearance on retail and decorative items.
- We have installed
imported controllers in our machines for better process stability, which
fewer defects and higher tolerance parts.
- Robotic sprue pickers on our machines help maintain more
stable cycles, reduce defects, and improve operator efficiency.
- More ejection pads than typical for small injection molding
machines in China protect your tooling, improving its lifetime and
reducing production delays caused by tooling problems.
- Our machines have additional safety features, beyond
those required by Chinese occupational regulations,
thus improving worker morale, and reducing overhead costs from
injury and death compensation. Many competing Chinese molding shops
have very high rates of worker injury and death, and have no
choice but to factor these expenses into their product prices.
To ensure quality production, workers are trained to visually inspect
all parts during production. Critical dimensions are measured every
half hour to one hour to ensure process drifts have not caused
dimensions to move out of tolerance. Production lots are spot checked
again before shipping to ensure conformance.
For medical items, food contact items, engineering parts, and other
safety-critical products, ensuring that correct materials are used in
production is critical. ChinaForge adheres to a strict system of
raw material storage and labeling to ensure that incorrect materials are
not used by mistake.
We take special care to properly store and maintain injection molds in
our possession to protect your investment. If you own an otherwise
quality tool that is
producing less than satisfactory parts at another Chinese injection
molder, consider moving it to our shop to see the quality difference.
