What Our Mold Making Service Includes
- Review part structure and production needs before tooling.
- Design mold structure based on part, material and cavity plan.
- Manufacture molds with CNC, EDM, wire cutting and fitting.
- Validate T1 samples for size, appearance and assembly.
- Optimize the mold based on sample results and feedback.
- Support trial production, mass production, inspection and packaging.
Why Do You Need a Mold Risk Review Before Tooling?
- 3D CAD does not always mean your part is mold-ready.
- Low tooling cost may hide production risks.
- Lack of DFM can lead to more T1 changes.
- Good samples still need production validation.
- Separate tooling and molding suppliers may create responsibility gaps.
What Is Injection Mold Making
Injection mold making converts your plastic part design into a production-ready tool for repeatable injection molding. Before tooling begins, the part is reviewed for wall thickness, draft angle, undercuts, gate location, parting line and assembly risks.
After mold design, the tool is manufactured by CNC Machining, EDM, wire cutting, polishing, fitting and assembly, then verified through T1 trial samples before production.
Mold Types Based on Production Plan
Different product stages require different tooling solutions. We help choose the right mold type based on your part design, expected volume, material, cost target and long-term production needs.
For product validation, functional testing and low-volume trial production before investing in full production tooling.
Built for stable long-term injection molding production, with mold structure, steel and cooling design selected based on expected volume.
Designed to improve production efficiency and reduce unit cost, especially when part structure, material and molding balance are suitable.
For plastic parts combined with metal inserts, soft-touch materials, two colors or two materials, with careful review of bonding and positioning risks.
Plastic Injection Mold Manufacturing Advantages
We help you turn custom plastic part designs into practical, production-ready mold solutions. From tooling strategy to long-term mold support, our goal is to make your mold project easier to manage and more reliable for production.
We support custom mold projects from product idea to stable injection molding production.
Mold making and injection molding are managed under one roof for clearer communication.
We support prototype molds, production molds and multi-cavity molds based on your production plan.
We provide mold storage, maintenance and production support for repeat orders.
Potential molding risks are identified early, helping reduce unnecessary mold changes later.
You receive molded samples to check fit, appearance, and basic performance before production.
The mold is developed for repeat production, helping keep molding results more consistent over time.
A well-built injection mold helps reduce rework, downtime, and avoidable production costs over the long term.
Injection Mold Projects With Practical Results
Learn how different mold projects go through engineering evaluation, mold manufacturing, and trial runs. Each project is tailored to your product design, expected production volume, and application requirements.
A German automotive parts supplier needed to develop a multi-cavity mold for small, precision plastic parts. After evaluating the product dimensions, material flow characteristics, and expected production volume, we recommended a 4-cavity mold solution, which helped the customer increase production efficiency by 40% while ensuring consistency across the different cavities.
One of our clients, an American electronics company, needed to develop a mold for a plastic housing with metal inserted parts. Before mold production began, TryCooler evaluated the positioning of the inserted parts, the sealing areas, and the assembly dimensions, helping the client limit the risk of part misalignment to within 0.2 mm and improve production stability.
An outdoor product brand wanted to make the handle more stable and provide a more premium feel without adding any extra assembly parts. TryCooler adjusted the design to a one-piece overmolded structure, optimized the soft touch rubber coverage area, and added a mechanical locking mechanism. This helped the client reduce manual assembly time from 5 days to 1 day and facilitated a smoother product launch.
Material and Mold Steel Selection Support
We help match plastic material, mold steel, surface finish and inspection requirements based on your product application, production volume and cost target.

How to Get Started with Our Custom Mold Making Service
Send your 3D drawing, 2D drawing, sample, photos, material requirement and estimated quantity for initial review.
We review the basic part structure, material feasibility, tooling direction, estimated cost range and project timeline.
Our engineers review wall thickness, draft angle, undercuts, gate location, parting line, shrinkage, warpage, assembly and tolerance risks before tooling.
After mold structure is confirmed, we move to mold design and manufacturing, including CNC, EDM, wire cutting, polishing, fitting and assembly.
T1 samples are molded and checked for dimensions, appearance, assembly and molding stability. If needed, we adjust the mold before approval.
After sample approval, we support trial production, mass production, quality inspection, packaging and shipment.
What Customers Say About Our Mold Making Service
Perfect, this was exactly the kind of support we needed before injection tooling. We sent TryCooler a 3D file, and their team helped us check the wall thickness, screw bosses and gate position before cutting steel. The first samples came out much closer to what we expected.
Mark HendersonProduct Manager, UK Home Product BrandThat helped a lot. In past projects, the mold maker and injection molding factory were separate, and sample issues took time to explain. With TryCooler, the tooling and molding teams worked together, so we could understand the T1 results much faster.
Jason MillerSourcing Manager, US Electronics CompanyThe final overmolded part looked great! At first, we only focused on the soft material, but TryCooler helped us review the grip area, locking structure and shut-off edge together. The part felt more stable and was much cleaner for launch.
Ethan CollinsProject Lead, Outdoor Product Brand
We usually need a 3D drawing such as STEP or STP for accurate evaluation. If available, please also provide 2D drawings, material requirements, surface finish, estimated quantity and application details. Samples, photos or sketches with dimensions are also helpful for early review.
Yes. Before tooling starts, our engineers review wall thickness, draft angle, undercuts, gate location, parting line, ejection, shrinkage, and assembly risks. This helps reduce unnecessary mold changes after T1 samples.
Mold lead time depends on part size, structure complexity, cavity number, steel selection and modification requirements. After reviewing your drawing, we can provide a more realistic tooling timeline and project schedule.
Mold cost is affected by part size, structure complexity, cavity number, mold steel, sliders, lifters, surface finish, tolerance and expected production volume. We recommend a tooling plan based on your production needs, not only the lowest mold price.
T1 samples are used to check dimensions, appearance, assembly and molding stability. If issues are found, we analyze whether they come from product design, mold structure or molding process, then suggest proper mold modification before production.
Yes. We can suggest suitable materials based on product strength, appearance, flexibility, transparency, temperature resistance, flame-retardant needs and application environment. Common options include ABS, PP, PC, PA, POM, PMMA, TPE, TPU and other engineering plastics.
For molds used in our factory for injection molding production, we can provide mold storage and maintenance support based on the agreed production plan.
Yes. We understand custom mold projects often involve confidential product designs. NDA or NNN agreements can be signed before reviewing drawings, samples or project details, and customer files will be handled as confidential project information.
