Quick Info

Silicone Rubber Molding is the most popular manufacturing method to produce flexible and durable parts. GEMS-MFG has been supplying silicone rubber products covering multiple industries, like automotive, medical equipment, mom & baby care, construction and consumer products.

Liquid Silicone Rubber (LSR) and High Consistency Rubber (HCR) are mainly used at our factories. As known to all, each kind of silicone rubber has its own advantages and disadvantages, so we will take full consideration to the property of strength, weathering resistance, oil/grease/fuel Resistance and working temperature, plus the cost of the material. GEMS team works closely with our client to discuss and finally choose the most appropriate material for the product.

Starting with your AutoCAD, IGES, PDF, or SolidWorks file, our expert team produces your custom parts with tight tolerances and that always meet your specifications. Regardless of the complexity of your design, we’ll find the best way to meet your needs in a timely, cost-effective manner.



  • There are always some demand of rigid plastics covered by soft qualities, such as handles, grips and toothbrushes, which make them feel more comfortable to use and reduce shock & vibration for the operation.
  • The common problem for overmolding is the poor adhesion between two materials, either soft or hard thermoplastics and the substrate. From our experience, the bond of two materials’ adhesion is mainly determined by their compatibility, so choosing the right material is extremely critical.
  • Parts with hard-soft combinations also get beyond restrictions imposed by traditional assembly methods. For instance, as electronic packages continue to shrink, installing seals that prevent moisture from seeping inside electrical components is becoming increasingly challenging. Molded hard-soft combinations may replace traditional seals and gaskets in some applications.


  • GEMS-MFG use the plastic injection molding technique to create the plastic components required for the personal care product parts, which are differing in size, complexity, and functionality. This process calls for the use of an injection molding machine, raw material, and a mold. Before being injected into the mold, where it takes on shape and cools to produce the finished product, the plastic is melted by the plastic injection molding machine.
  • Every year there are thousands of personal care items are newly released to the market. With the help of cutting-edge technology, our team strive to maintain the position being a leader in the development of custom injection molds and injection molding parts that can be used to produce any personal care plastic product.
  • Along with plastic injection molding, we are capable of offering engineers, parts design, mold design, mold fabrication and product assembly services to execute any project in accordance with the standards and needs of your industry.


  • Providing silicone rubber injection molding for numerous maternity and baby related products is one of our manufacturing specialties. Below are just a handful of the numerous items available, like bottles, spoons, sleeves, combs, hairbrushes, plates, and cups. You can trust that we are supplying the greatest and highest quality products for your kid, because all of our products are safety inspected and baby-proofed.
  • It is crucial to us that we work with your company to develop durable, functional mom and baby products made through plastic injection molding. We pay close attention to the design, safety, aesthetics, and functionality of your products. We take pride in the maternity and baby industry and keep providing great products that make it easier for parents to take care of their children.
  • Visit our factory to learn more about the services we offer and you will get better idea why GEMS-MFG ranks among the top injection molding companies. We will keep providing customers with the best quality products & services that both meet and exceed expectations.


  • At certain point in our lives most people will come into contact with liquid silicone injection molding product or parts, frequently without even recognizing it. Despite the hardness and durability of hard plastics, there are products require a somewhat softer touch to guarantee that users are comfortable. In addition, liquid silicone molding is well known for its outstanding accuracy and consistency, also cost-effectiveness with high volume production.
  • Product designers for medical Industry typically focus on function, appearance and ergonomics, while designing for manufacturability (DFM) is an important criterion from GEMS-MFG’s engineering perspective. We can reduce inefficiencies or potential issues before massive production by using a variety of methods and concepts, including mold flow analysis, prototyping, scientific molding analysis, and automation consideration. The process of medical plastic molding surely produces the greatest lab equipment and medical devices with the highest level of quality assurance.
  • We are very family with many key manufacturing processes for the medical industry, such as precision mold making, high gloss molding, 2k injection molding, liquid silicone molding and various surface finishing methods like pad printing and electroplating. Our team is well prepared and excited to start with your concept and turn it into a reality.


Integrated Factory Resources

We are your one-stop manufacturing solution provider for customized products with the joint effort & support from our 120 partnership subcontractors mainly for the production of metals & plastics. We can expand much faster but the top management decide to keep GEMS a compact, dedicated and professional company, which allows our team to really focus and deliver on your projects without any excuse or compromise. We strive to be a long-term, reliable and trustworthy partner of our customers rather than just being a contractor, and look forward to growing the company with customers’ success.

Manufacturing Veteran Team

With the passing years, we are proud to build up a manufacturing veteran team with rich experience and full expertise to fulfill your specific demand. From mold making, injection molding, die casting, stamping and sheet metal, to 2nd processes like CNC machining, oil spraying, powder coating and chrome plating, and then assembling and packaging and related, we always have someone in house to be an expert to resolve the issues in different stages of product development. We also specialize in providing charger, cable and hub, plus other electronic accessories that support a complete set of product.

Strong Project Management

“Think global, act local” is the principle of our work. Time, quality and cost are the three key elements to be considered throughout the product development from concept design to mass production. A detailed plan with weekly conference call update is a critical gateway to ensure these three key elements are successfully implemented, also assuring that all parties are on the same page. Communication is the Secret to Success . Everyone works independently to take care his own job, but together we are a team to get things done and are your daily eyes and ears onsite in China.

Flexible Operation & Customization

We offer a wide variety of products, such as mold, component and assembly product, and certain value-added services. For logo or branding product, we have in house resources to complete a color mix that can perfectly match a brand’s unique colors in fast and cost-effective way. Understood the client needs production parts but having a hard time to find a vendor since the order quantity is as low as 1000 or lower. GEMS is well set up for low volume injection molding or die casting projects. Surely our team is also capable of building SPI Class 101 mold that is designed & made for 1 million cycles or more of producing the same high quality parts consistently.
