Learn More About Xcentric Mold & Engineering

We’ve seen a need out there for the product developers to help get their parts to market quickly…where our specialty is helping the customer get through the prototype stage and ramping them into production.

Hi, I’m Brendan Weaver from Xcentric Mold & Engineering and we specialize in Real Fast Custom Parts.

What does Xcentric do?
We offer quick-turn injection molding from 1-15 days and CNC machining from 1-10 days.

What benefit do you provide your customer?
We help streamline the quoting process where we can educate the customer on materials, we offer custom colors, custom finishes and engraving. With Xcentric and because of our capabilities we don’t put any limitations with how many parts you can get off our tools, as long as we build it, we run it, we give it Lifetime Mold Guarantee.

I don’t want you to change your design to make it easy for us to make your part. Our system will allow us to make your part the way you need to.

Overmolded Parts

Overmolded Part

Do you have any examples?
This is an overmolded part. A customer needed rubber put onto hard plastic and we were able to turn this quote around within a day and, from a purchase order, able to get the parts in the customers hands in 15 days.  We are doing insert molding and overmolding.

What is overmolding?
Overmolding is when you take a hard plastic material and you’re going to put a softer type of plastic on it. What’s overmolded on this is the rubber and these little lenses. So this is actually a three-piece assembly all molded in.

What is insert molding?
Insert molding is when you’re taking inserts and loading them into the tool and putting the plastic around it. And we are molding in the inserts during the molding process.

It doesn’t matter if it’s off-the-shelf insert or custom insert, we can insert mold anything.

What tolerances can you achieve?
A typical tolerance is +/- 0.005″. With our process we can achieve +/- 0.001″

Do you have any certifications?
We are ISO 9001:2008 certified and will be transitioning into the 9001:2015. We are also UL and ITAR registered.

What are some of the things you can do with your CNC machining service?
Let me show you some metal CNC machining. We are doing external threads so we can do thread grinding. We can also do aluminum with tapped holes so if you have threads in your holes we can do that. Any type of feature that has to come in from the side, that’s where our 5-axis machining capabilities come in at. We can also do custom finishes, chrome plating, laser etching.

What size parts can you produce?
On the CNC side, it’s up to 36 inches. On the injection molding side it’s up to 32oz. shot size (typically 24″ x 24″ x 5″ deep part)

How long have you been in business?
We’ve been in business for 20 years but our quick-turn development process that we’ve been really streamlined on has been our niche for the last 10 years.

The Difference Between Moldability and Manufacturability

The difference between moldability and manufacturability may seem subtle, but the reality is that understanding it better can have an impact on your part development.

What is Moldability?

moldabilityMoldability refers to how well the mold of your part will conform to being injected with molten plastic. Once your mold has been created from your design, a good injection molding process needs to account for how well plastic can fill that mold cavity.  From material selection to mold complexity, there are many factors that will determine whether the part you designed is capable of accepting this process.  Certain features in your part design like undercuts and threading, can be tricky to mold correctly and consistently.   These can cause problems like knit lines, warp and flash.


Xcentric Mold vs. 3D Printed Mold

How do 3D printing molds match-up against Xcentric’s Advanced Mold Making and Proprietary Process Engine?

3D printing has come a long way in recent years.  According to IBIS World, it is currently a $492.4 million market and is expected to grow by 80% over the next five years.  This sort of growth will open up all kinds of new applications for 3D printing.  In fact, NASA has already experimented with using this technology with the hope that they can begin to establish on-demand machine shops…in space.  We’ll be doing the Kessel Run in under 12 parsecs in no time.  🙂

So, at this point, what can’t 3D printing do?

3 Easy Ways To Speed Up Your Development Cycle

Here are a few tips you can easily implement to help to cut your development by up to 50% from conventional manufacturing.

  1. Utilize a Manufacturability Analysis – If Injection Molding is the right manufacturing process for your project, you can limit the amount of redesign work by quickly addressing problematic areas in your part while expediting the production process.


The Importance of Design for Manufacturability

Design for Manufacturability (DFM) is the proactive process of designing a part to meet the specifications of the chosen manufacturing process used to produce that part. No longer can a product engineer design a part for fit and function only. Product Engineers are also expected to understand the manufacturing process and incorporate those parameters into their design to ensure good part production.

Ignoring design for manufacturability can have disastrous consequences. By the time a product concept gets through the design phase and into the testing/prototyping phase, up to 80% of the budget for that product has been committed. The material costs have been identified, the tooling costs are known and any assembly costs are also worked into the budget by then. And once it has been committed, it is very expensive to turn back to change the design.

How Two Brothers Reshaped an Industry


Brendan and Damon Weaver aspired to be the best mold makers in the industry. It was Autumn of 1996.

They had both been working at the same company and had utilized the available 3D CAD software and CNC technology at the time. But unfortunately, they had pushed themselves to their limits with their employer and felt that they were being held back by the lack luster advancements of a 100 year-old industry.

They were determined to make it better.
