Full Service Manufacturing
Engineering Service for Custom Plastic Parts in the USA
A thick section in a plastic part can cool differently than the thinner walls around it, and a vertical surface without enough draft can resist release from the mold. Our engineers can account for details like these when your team still has room to refine the design before developing the tooling.
At Design Plastics, we have an experienced team of industry specialists who provide a precision-based engineering service for injection-molded and vacuum-formed plastic parts across the USA. We’ll work directly with you to develop a new component or prepare an existing design for the manufacturing process we’ll use.
Part quality is impacted long before the press closes. The design, the tooling built around it, and the plan for running it all determine how a component performs and how easily it can be made. Design Plastics works across all three, with in-house engineering, tooling, custom injection molding, and thermoforming for customers nationwide.
What Are Engineering Services?
When you need a custom plastic part, you need engineering support to turn that blueprint into the component your product requires. Our engineers will first learn what the part needs to accomplish within your finished product. We’ll then refine the design around the material and molding process we plan to use, so the part forms correctly and releases from the tooling.
We can provide that same support for a component you already manufacture. If the current design needs to suit a different application or production process, we’ll help you adapt it without sacrificing what already works.
Key Engineering Services
Our team provides engineering assistance at the points where design decisions are going to directly influence any tooling and manufacturing processes, as well as the finished component. We’ll help develop the part’s geometry, evaluate materials according to its intended use, and prepare the design for injection molding or vacuum forming.
Our engineered molding technology includes CAD and CAM capabilities that allow us to create accurate 3D models and simulations. We can also design forming tools for vacuum-formed parts and produce prototypes for evaluation. For injection-molded parts, we review and approve the tooling through the DFM process and coordinate mold-flow analysis with our toolmakers when needed. We also use CNC machining for our vacuum-forming and forming-tool work.
Our Engineering Workflow
We’ll first learn what the component needs to do, where it will fit, and which physical conditions it could encounter during use. Our engineers will then review the design and determine how its geometry and material will respond to the selected manufacturing process.
From there, we can develop the digital model, refine the part for manufacturing, and design the necessary mold or tooling. Our engineered molding solutions can include prototyping, testing, or mold flow analysis to help us evaluate the design before moving into production.
Why Partner With Design Plastics?
As an engineering service company with injection molding, vacuum forming, tooling, and CNC capabilities as our core services, our team at Design Plastics has an in-depth understanding of how our equipment will interact with the part our engineers help you develop. This lets us account for all manufacturing requirements during the design phase rather than handing the component off to a separate production team later.
You’ll stay directly involved as we evaluate the part and prepare it for manufacturing. Our engineers will explain what we find, discuss any proposed changes with your team, and keep the finished product’s function at the center of each decision.
Develop Your Plastic Part With Our Engineers
Whether you have an early concept or a developed component, our engineers are ready to examine what the part needs before you commit to the mold or tooling. We’ll apply our experience with plastic materials, part geometry, injection molding, vacuum forming, and production equipment to the specific design you bring us.
Tell us what you’re developing and where you currently are in the process. Contact us today to discuss your plastic part with our engineering specialists and request a quote for your project.
Frequently Asked Questions
How Does Mold Flow Analysis Benefit My Project?
When a project calls for mold-flow analysis, we can coordinate it with our toolmakers. The analysis shows how molten plastic is expected to travel through an injection mold and fill its cavity. We can then review the findings with you and discuss any recommended changes to the part or tooling before manufacturing begins.
Can You Assist With Material Selection?
Absolutely. We’ll consider what your part needs to do, the conditions it could encounter, and how different materials will respond during manufacturing. Its geometry, strength requirements, flexibility, appearance, and intended use can all influence the material we recommend for your injection molding or vacuum-forming project.
Is Design Plastics ISO Certified?
Yes, we are ISO 9001 certified. Our team follows our certified quality management system to control our processes, evaluate our work, and achieve consistent results. We apply those requirements throughout our operation rather than treating the certification as a credential that sits apart from how we manufacture plastic parts.
Can You Improve an Existing Part Design?
We certainly can. Our engineers can review an existing component according to its intended function and the process we’ll use to manufacture it. If its geometry, material, tooling requirements, or relationship with adjoining parts warrants a change, we’ll explain the reason and help your team refine the design before production.
