Forwa-Mould , locating in Dongguan, China, is a professional
plastic injection mould manufacturer with years experience in this
field. We can provide high precision complex hardened moulds,
prototype and soft moulds.
We equipped high speed CNCs, Wire cuts in house. We use software
(i.e. UG, Pro-E, IGS, Master Cam, AutoCAD, and Solidwork ) for
mould design and MoldFlow analysis for our customers before mould
manufacturing. Standard components we use to build the mould are
purchased from DME, HASCO etc. Also, COC for all steel we purchase
will be provided.
Mold Threads empowers engineers to achieve their vision for custom
molded parts in function, durability, and quality while maintaining
the integrity of the design.
Mold Threads' passion for quality has made us a leader in the
design, tooling, and molding of injected molded parts.Component
parts that are critical in the manufacturing of products for a wide
arrage of industries and applications including:
- Point-of Purchase
Producing plastics parts with undercuts presents distinct
challenges for molders. Undercuts are protrusions or recessions in
a part that prevent the mold, after the part is formed, from
sliding away along the parting direction. These features inhibit
the direct removal of the core, and as a result, generally
necessitate using an additional mold piece, such as a side-core or
an internal core lifter, to form the shape.
Undercut designs are often used to create threaded parts, such as
screw-on bottle caps, snap-on products such as lipstick containers,
and a variety of consumer, medical, automotive, and other products.
Threaded caps illustrate well the complexities associated with
undercuts. After the cap is formed, the threads of the part and the
threads of the core are intermeshed and must be disengaged before
the core can be pulled out and the cap removed from the mold.
Molders have developed a variety of methods for molding undercut or
threaded parts—some as simple as unscrewing the part by hand or
machining the undercuts in a separate operation—that range widely
in cost-effectiveness and efficiency. This article will present
some of the recent technology advancements that give molders
better, more cost-efficient methods of producing undercut or
Unscrewing molds are among the most complex of all injection molds,
requiring considerable technical savvy to build and maintain. They
are usually built for many years of production and are considered a
long-term investment for producing high-volume parts.
