Precision Metal Stamping Parts and OEM Plastic Parts for Reliable Production

We are aware of how time wastage in production and unreliable parts hurt timetables and profitability. Our expertise in OEM plastic parts secures consistent fit, finish and function from prototype through volume production. The first time through stage gates and process controls are robust in order to achieve compliance to specification and inspection.

Why our approach works

We integrate engineering controlled tooling, contemporary presses and stringent quality inspections to provide repeat performance. For jobs that demand fine detail or high cycle life, Metal Stamping Parts made from stainless steel, aluminum or brass are an ideal choice. Stamping is a cold deformation process which shapes sheet metal in dies to accurate shapes with minimum machining effort.

Metal Stamping Parts — Materials, Process, and Uses

Materials: Stainless steel, aluminum, brass and steel. Surface finishes: zinc plated, chrome plated, anodize, powder coat and custom finishes. Processes: stamping, bending, laser cutting and secondary forming. Typical applications include automotive components, electronic housings, household appliances, LED lamp parts and precision assemblies.

Product description

We manufacture our Metal Stamping Parts using highly controlled dimensionality and maintained tooling to guarantee performance and interchangeability. Stamping components in industries are shaped using both conventional and progressive dies, which are selected according to complexity and requirements of the cycles. Our standard lead time is 30 days and payment term T/T, we accept custom sizes and finishes. We can test our samples and small runs.

OEM plastic parts services

We provide end-to-end OEM plastic parts capabilities: mold design, injection molding, finishing and assembly. Our engineers enable the optimization 

of wall thickness, rib structures and location of gates to minimize sink, warpage and cycle time. We accommodate all types of polymers and can match color, texture and flame rating as needed. When assemblies combine stamped metal and molded components, we match tolerances to provide clean, repeatable fits.

Why customers choose us

Clients value our engineering reviews, fast prototyping and transparent cost breakdowns. CN MOLDS helps teams lower assembly time and improve first-pass yield by combining consistent Stamping Parts with tight-tolerance OEM plastic parts. Our project managers keep communication short, clear and solution-focused throughout the program.

Prototyping and validation

We carry out tool trials and sample inspections before we commit to full production. Prototype parts enable form, fit and function checks and mitigate against expensive rework. In complex assemblies we can provide functional prototypes to test, then cycle tooling to production tolerance bands.

 This controlled process reduces the time between the approval and the qualified production.

Design for manufacturability

Our design group collaborates with customers to streamline assemblies and reduce parts and enhance yield. Our fillet changes, draft, and bend relief changes enhance stampability or molding characteristics without functionality loss. This partnership reduces the timeframes and reduces overall cost of ownership without losing the functional intent of the part.

Quality assurance and compliance

We use ISO-type inspection plans, in process checks and final dimensional reports. CMM measures critical tolerances which are recorded to provide traceability. We carry out process capability studies in our teams to verify stability in production to pre-handover. Our stamped components minimise downstream rework and assembly time when you need reliable yields.

Choosing the best material and finish

Choosing an alloy and surface treatment is the way to live longer and simplify the process of assembling. Aluminum stamping components are lightweight and corrosion free. Heavy-duty uses of the stainless steel parts ensure strength and wear resistance. Finishes like zinc plating or anodizing provide corrosion resistance and beauty and achieve the appearance and durability your product needs.

Tooling and lifecycle support

Maintenance of tools and periodic rework maintain production at run-to-run. We offer tooling inspection reports and suggest times of the maintenance according to the estimates of the number of shots. In progressive dies and injection molds, proactive maintenance maintains part quality and minimizes the unplanned downtime.

Cost and lead time guidance

The maintenance of the tools and regular rework maintain the production stability between the runs. We submit tooling inspection reports and suggest intervals of maintenance on the basis of forecasted shot counts. In progressive dies and injection molds, scheduled maintenance maintains quality of the parts and minimizes unscheduled downtime.

Frequently asked questions

Q: What are the file formats that you accept in quotes?

A: STEP, DWG and DXF are all accepted to stamp parts and solid model of plastic parts to generate manufacturable tooling recommendations.

Q: Are you able to deal with small and large volumes of production?

A: Yes. We uphold prototype quantities and the high volume output using progressive dies and automated forming cells.

Q: What are the surface treatments that exist?

A: Some of the standard ones are zinc plating, chrome plating, anodize and powder coat. Individual coatings are available at a quote.

Q: What do you do in regards to part uniformity?

A: Tolerances and repeatability across batches are maintained with the help of validated dies, SPC charts, and CMM verification.

Q: Do you have assembly and packaging?

A: Yes. We offer assembly, inspection and custom packaging to satisfy delivery and handling requirements.
