Injection Molding Mold Design


Cindre is not a design company,  we are a plastic mold and molding manufacturing company geared to help you bring your product ideas to life.

Injection Mold Design and Mold Tooling


We are an American professional mold manufacturer specializing in injection mold tool design of large and complex injection moulds and then making them. 



Our core business strategy is to provide one-stop injection moulding solutions, including mold design, mold making, plastic parts manufacturing and secondary processing services, utilizing our offshore partners to help in designing a plastic injection mold and making this mold providing optimum value  to you, our customer.

Irrespective of your expertise in designing parts for injection molding, collaborating with a skilled mold maker will streamline the design process. Each mold maker has distinct tooling preferences and techniques that can greatly influence the detailed design requirements of the part.

For your plastic mold design needs, Cindre can always deliver professional outcomes, our experienced team of designers and engineers can confidently meet your specifications.

Even though we don’t offer fee based, standalone design services as a product design company anymore, plastic injection mold design is our core competency, so we can assist your manufacturing project with our design and injection molding mold design expertise.

 Specify your needs and we’ll craft a cutting-edge prototype design just for you.

Tangible Concept and Functional Parts

In a few weeks only, obtain and handle real samples of your new product. 

While designing and manufacturing moulds, our team performs tasks of great complexity, using our injection molding process and following your requirements and using the most up-to-date software tools and equipment.

Injection Mold Making

After finalizing the mold design, the mold is created using appropriate tooling. Through mold testing and monitoring processes, we guarantee the production of top-notch parts. This could entail manufacturing a limited number of parts and examining them for flaws using cleanroom injection molding. Additional optimization might be necessary based on any identified defects.

Produce Quality plastic Parts with Custom Injection Molds and Expert Design Assistance

Establishing a solid connection between your company and your injection molding collaborator prior to design is crucial for part effectiveness and adherence.

At Cindre, we guarantee precision crafted parts for your all your volume components, be it for one thousand or thousands and thousands of parts; by enhancing processes, maintaining quality, selecting materials expertly, and most importantly, designing molds guided by proven industry standards.

Don’t wait to improve the design of your injection molds by making slight product alterations, instead, catch possible manufacturing defects and lower production expenses.

Comprehensive injection mold design services

At Cindre we provide comprehensive mold design services.

 Such services are rendered at a fee of US$500 that is 80% credited toward the purchase of a mold from us, unless a mould order is placed up front, in which case the mold design is included in the cost of the mold. 

This service involves the planning, creation, and optimization of molds used in the manufacturing process, specifically for molding materials into desired shapes and sizes.

The correct design of a mold can significantly influence the quality, consistency, and efficiency of the production process, and tends to show deficiencies in the product’s design specifications and design features resulting from designing a part incorrectly from a manufacturability point of view as well, if any.  

Here are some key aspects of the services we offer for designing moulds:

Custom Injection Mold Design

At Cindre, we have a small, very experienced team of skilled injection mold engineers, both state side and in China, who are dedicated to the design of molds being mindful of all design considerations of the most detailed mold component.

Our focus is on designing and manufacturing molds that are not only incorporate design for manufacturability and precision, but also precise, ensuring they match the design guidelines and exact specifications of your part design. We prioritize longevity and value, which is why we use top-notch, durable materials in our mold production to guarantee long-lasting performance over numerous production cycles.

Mold Gate Design

The injection mold’s gating system being designed with best practices in mind, is crucial for achieving high-quality molds and products by allowing the molten plastic to enter the mold by flowing to and filling the mold. 

The design of the gating system directly affects product quality, including factors like appearance, warping, weld lines where the two halves of the mold come together when the mold closes, flow marks, and trapped gas. 

It’s important to ensure the gating system is well-thought-out to produce top-notch results.

Mold Cooling System Design

Investing in a top-notch cooling system for the mold core can lead to faster molding cycles, higher production output, and lower expenses. 

On the other hand, a poorly designed cooling system will slow down the molding process, drive up costs, and result in warped products due to uneven cooling. 

It’s crucial to prioritize an efficient cooling system to maximize productivity and minimize expenses in the long run.

Injection Molding System Design

Ensuring the proper design of the molding system, and how the mold is designed is crucial, as it can directly impact every aspect of the manufacturing process used to produce plastic parts, from mold-making to injection molding, and even the final appearance and performance of parts that require the highest level of attention.

Our dedicated engineers give their full attention and expertise to important design considerations when creating each half of the mold cavity, the parting line where the upper and lower parts of the mold come together, the runner system, as well as the uniform wall thickness resulting in realizing the part’s design intentions without a sink mark blemishing the exterior of the part’s outer plastic surface of the part. 

From where the plastic resin turns to a plastic flow, to where the plastic is injected, the whole area of the part, literally every side of the part, no matter what size of the part, including things like the injection pressure the part requires, is considered by us, guaranteeing the highest quality product possible when the part is ejected from the mold when the mold halves open and the plastic products are finally born.

Ejector System Design

The effectiveness of the ejector system is crucial in shaping the quality and outcome of the final product.

Any flaws in the ejector pin system driven by the mold engineering and the injection molder resulting in a flawed ejection from the mold when the mold opens, can lead to defects in the plastic material such as deformities, discoloration, or even breakage.

With a decade of expertise in designing molds, Cindre has the expertise to ensure a flawless ejector pin system layout for your project.


We will guide you through the process of plastic part design and mold construction designed for high volume of plastic part fabrication.



Our design tips for the design for manufacturing injection molds will allow you to scale your production of high precision injection molded parts and compenents with very good repeatability.
