We build our molds to meet the highest customer standards for quality and reliability, designed to withstand high volume production with minimal maintenance. we always use mould bases and standard components such as LKM, DME, HASCO, FUTABA etc. and We always use high quality steels such as 1.2311,1.2738,1.2343 and 1.2344 from Saarstahl of Germany,718, 738, S136 and 8407 from ASSAB of Sweden, P20, 420 from USA and NAK80,SKD61 and SKD11 from DAIDO of Japan
With rich experience of many kinds of mold construction and mechanism, Sino-Mold is able to construct a wide variety of molds and components that will work efficiently, effectively and accurately, while at the same time keeping the customer's cost as low as possible. Minimum material waste, reduction or elimination of scrap, low maintenance, and long mold life are the standards in a well built mold.
We are familiar with Hot runner systems such as MOULD MASTER, HUSKY, HASCO, DME, YUDO, THERMOPLAY, With Hot Runner system you can eliminate sprues and runners, decrease cycle time per part, improve consistency in the part, and allow for better control of the overall molding process.
Our capability including: General plastic injection mold,two shot mold, insert mold,over mold,Die casting, rubber compression mold, IMD.
♣ Double injection Mold
Two Shot Molds (also three and four-shot) are a cost-effective method to produce plastic parts with two or more colors molded at the same time, such as radio control buttons or dashboard faceplates.
Two Shot mold is a relatively new, rapidly growing technology. It is replacing older, two step systems, eliminating a secondary process to add logos, graphics or text. New computer technology and advanced materials have promoted the growth of the two-shot process.
The two shot process first injects one color material into the mold, then injects the second color around or over the first. There are also multi-shot processes for parts with more than two colors (tail-lights can have up to four colors, for example).
The two shot process allows you to:
♥ Increase product features
♥ Enhances design aesthetics
♥ Reduce assembly steps and costs
♥ Improve quality
♥ Reduce cost per part
Some of the benefits of producing plastic parts using a multi-shot molding process includes:
♥ Produce more complex parts
♥ Produce multi-colored or multi-resin parts
♥ Parts with movable segments or components using on-mold assembly?
♥ Eliminate post-molding assemblies, such as:
Ω Snap-fits
Ω Ultrasonic welding
Ω Adhesives
Ω Screws or bolts
Ω Allows the first material to cool before the second one is injected
Designers and engineers are constantly coming up with new uses for plastic parts produced with the two, three or four step molding process. Just a few of the many types of these products include:
♥ Multi-color parts
♥ Toys with movable parts
♥ Flexible hinges
♥ Parts with seals molded into plastic
♥ Soft grip handle inserts
♥ Automotive A/C or heater louvers
♣ Insert mold
Insert Mold is an injection molding process that utilizes an insert placed in the molding cavity.
A molecular bond is established when using materials that are similar to the surrounding resin. A mechanical bond is established when using materials that are dissimilar to the surrounding resin. When comparing the two, for obvious reasons the molecular bond is stronger than the mechanical. For best results in using the mechanical bond process, it is important to use an insert that is capable of handling the surrounding plastic.
Insert molding can be used for molding fasteners, pins and terminals, and is widely used for molding parts needed in constructing medical equipment.
♣ Over mold
Over mold combines plastics with materials like rubber to form a completed part. It's a two step process, the over molding process uses a pre-formed plastic part placed into a mold. The second material is then injected into the mold, covering all or part of the first part. Over molding is a good choice if you want to mold a rubber piece onto a piece of hard plastic."
♣ Die Casting
Yipin Co.,Ltd is able to produce aluminum and zinc die-castings for various applications in industrial, consumer, agricultural, and automotive sectors. We have hot and cold chamber die casting machines with the necessary supporting equipment to manufacture die castings to meet customers' quality and specification requirements.
♣ Compression Mold
A method of molding in which the molding material, generally preheated, is first placed in an open, heated mold cavity. The mold is closed with a top force or plug member, pressure is applied to force the material into contact with all mold areas, and heat and pressure are maintained until the molding material has cured. The process employs thermosetting resins in a partially cured stage, either in the form of granules, putty-like masses, or preforms. Compression molding is a high-volume, high-pressure method suitable for molding complex, high-strength fiberglass reinforcements. Advanced composite thermoplastics can also be compression molded with unidirectional tapes, woven fabrics, randomly orientated fiber mat or chopped strand. The advantage of compression molding is its ability to mold large, fairly intricate parts. Compression molding produces fewer knit lines and less fiber-length degradation than injection molding.
