Frequently Asked Questions About Assembly & Secondary Operations
Get answers to common questions about our assembly and secondary operations services. If you need additional information, our team is ready to assist with your specific requirements.
What is the difference between primary and secondary operations?
Primary operations refer to the initial manufacturing process such as injection molding, where raw plastic material is formed into components. Secondary operations are the subsequent processes performed on these molded parts, including assembly, hot stamping, pad printing, painting, and other finishing processes. Secondary operations enhance functionality, appearance, or prepare components for final use.
Can Norco assemble components they didn't manufacture?
Yes, Norco can provide assembly services for components we did not manufacture. While there are significant advantages to having us handle both injection molding and assembly (such as streamlined logistics and consistent quality control), we have the expertise and equipment to assemble components from multiple sources. Our team will work with you to ensure all parts meet specifications before assembly.
What decoration options are available for plastic parts?
We offer several decoration options for plastic parts, including hot stamping, pad printing, screen printing, and labeling. Hot stamping provides metallic finishes, textures, and patterns with excellent durability. Pad printing allows for multi-color designs on curved or irregular surfaces. Our team can help determine the optimal decoration method based on your part geometry, material, and design requirements.
What industries typically require assembly services?
Assembly services are utilized across numerous industries including consumer products, automotive, medical devices, electronics, construction, and industrial equipment. Any industry that requires finished products composed of multiple components can benefit from professional assembly services. Our expertise spans these diverse sectors, providing tailored assembly solutions that meet industry-specific requirements and standards.
How does assembly affect the total cost of production?
While assembly adds an additional step to the manufacturing process, consolidating molding and assembly with a single vendor often reduces overall production costs. This approach eliminates shipping between facilities, reduces handling damage, streamlines quality control, and minimizes administrative overhead. Our integrated approach typically results in 15-30% lower total production costs compared to using separate vendors for molding and assembly.
What quality control measures are used during assembly?
Our assembly operations include comprehensive quality control measures such as in-process inspections, first article approvals, dimensional verification, functional testing, and final visual inspection. We use precision measurement equipment including coordinate measuring machines (CMM) with accuracy to ±0.0001 inches. Each project has a customized quality plan that ensures assembled products meet all specifications and performance requirements.
