Turnkey LSR capabilities-design, Prototyping, Tooling and Injection Molding Manufacturing Company

XTmade has been committed to meeting our customers' custom molded rubber needs. Our expertise enables us to provide solutions to the most difficult applications.

Our focus at XTmade is service to our customers. Whether your needs are for 10 pieces or millions, we will establish a partnership with you from the beginning. In this way, we can work as a team to create your exact needs. Your specific requirements are considered throughout every stage of the project.

If you’re looking for a proven design to injection molding manufacturing resource for your custom LSR projects, our company has you covered. LSR is among a large portfolio of elastomers our customers spec for projects requiring unique properties. For example, in medical device applications LSR is a common material choice because of its biocompatibility with body tissue.

Experts within our advanced materials lab can help you make the right materials choices. Our materials scientists are experts in the full range of platinum cured silicones and peroxide cured silicones. One of our materials scientists will help you determine if the on-spec requirements are the best choice for the application, or if an alternative off-spec material choice will provide a higher level of quality, reliability and performance to the end product.

From designing, prototyping, tooling management, manufacturing, and distribution, we comply with all regulatory guidelines, including ISO 13485 and 21CFR820.

advanced manufacturing


Benefit from our ultra-modern extrusion equipment to create the perfect profile for your application. We offer custom shapes, specialty rubber compounds, as well as secondary manufacturing and assembly services.


Think collaborative problem solving. By letting us become an extension of your team, we can truly put our of experience at your service. Let’s discuss what our ingenuity can do for you.
Fast delivery


Turnaround times for custom seals vary from days to weeks. And they have a huge impact on inventory costs. Shorter lead times are also a great advantage when you’re dealing with unpredictable demand forecasting.
easy cooperation


It doesn’t have to be hard. And with XTmade, frankly, it isn’t. You’ll find us proactive, flexible, dependable and true to our word. The unpredictable nature of custom work demands nothing less than our best effort.

Liquid Silicone Rubber Molding Capabilities

We’ll Help You Avoid and Mitigate Significant Risks in LSR Projects

We’ll collaborate with you early in a project to help you consider quality and certifications to avoid rework that increases cost and delays projects. Rely on us to:

  • Consult with you on the prototype to consider long-term production engineering needs.
  • Help you consider all your material options before advancing to the next stage of the project.
  • Review the key functional features with you such as parting lines and gating locations.
  • Help you with specifications to ensure they are not overly constrained.

The more we work together and share information the more our experts can help anticipate your needs and avoid and mitigate risks to your project.

Designing and Creating LSR Prototypes with Manufacturing in Mind

Some customers call us after they discover the prototype they contracted to build was delivered with a minor flaw: unfortunately it couldn’t be manufactured. You’d be surprised how often that happens; in the haste to build a quick prototype, designers/engineers with limited elastomer experience end up with a seemingly perfect design, yet it’s impossible to manufacture at scale.

We collaborate with you early in the project to focus on quality and better understand the design input and output  requirements of your custom parts. Allowing us to better understand the design intent of the product, will lead to a smoother product launch, greatly reducing future risk.  Examples of questions we will help you answer include:

  • Do you need an early-stage prototype or a manufacturing-quality replicate prototype?
  • How many cavities will be needed in the tool to support the volumes needed for development?
  • Where are your critical sealing surfaces and functional areas?
  • Where can we place gates and parting lines?
  • What are the general operating conditions as to temperature, fluid contact, cycles rates?

Unlimited design capabilities

We rely on in-house tooling and sophisticated process engineering to improve quality and ensure the consistent achievement of tight tolerances while delivering the lowest cost of ownership for our customers.

We are your go to source for custom molded rubber and silicone products.

shop; Not temporary tooling like other companies. Then, we take the project from prototyping to completed production. You never have to have another company enter the production process. Some of the services we offer are: 

  • The fastest complete silicone services from proto to production. 
  • Your custom tooling is made in house from 4130 steel to create the best precision steel tooling with the best lifecycle cost
  • Our custom molding services include injection, transfer, and compression molding abilities. 
  • The production of overmolded parts isn’t just a major part of our business. It’s a specialty of ours.
  • Our custom rubber molding can be done for either high volume or low volume production. We don’t shy away from very large orders and we proudly accept orders that are too small for our competitors. 
  • We offer a varied list of services for rubber to metal bonded and custom silicone to metal bonded items. We can bond any of our custom formulas to materials such as brass, aluminum, steel, and even glass filled nylon to match your needs perfectly. 
Silicone Molding


Some applications benefiting from LSR injection molding include:

  • Medical device and patient interface components
  • LED lenses and optics
  • Electrical connectors and seals
  • Infant bottle nipples, pacifiers, and toys
  • Plumbing gaskets and seals
  • Soft touch buttons/handles and appliance components
  • Consumer goods
  • Food and beverage preparation, dispensing and utensils

Advantages of Liquid Silicone Rubber (LSR) Molding

LSR injection molding offers custom manufacturing opportunities and is a sought-after solution due to its ability to mold complex part geometries, excellent mechanical properties, and purity. Other benefits include:

  • High tear strength
  • Great optical clarity to maximize light transmittance
  • UV resistant
  • Biocompatible
  • Low compression set
  • Excellent chemical resistance
  • Withstands harsh environments ranging from low to high temperature extremes
  • Ability to overmold and bond onto a variety of substrates, such as plastics and metals
  • Customizable additives such as antimicrobial, electrical conduction, self-lubricating and antistatic
