Finished products install and package is a comprehensive department in the industrial factory, All parts are reached at this place at last after passing a few processes. whenever metal parts or plastic plastic, operators begin to have a right installment and testing under a right guideline. Some Metal parts may be installed together with screws. inside put some of plastic parts if necessary. something like this , a finished products is gone. But also in accordance with client’s requirements, worker put some finished products into accordingly packaging box and cartons. This is the main occupation of the department. They either control the quality of finished products or package these products in right way.
- Check outsourcing coated parts surface appearance
- Install zinc alloy parts into a finished product or functional part
- Assembly zinc alloy parts and plastic parts together and become a finished product
- Fit embed part out of zinc alloy parts and complete a process
- Install electronic components into plastic parts and have a trail testing
- Record the quantity of finished products and unfinished products process
- Put the finished products and parts into reasonable packaging vessel and cartons
- Sort out different category of products ,especially Good products and No good products
Check outsourcing coated parts surface appearance
TangSheng Hardware Technology produce mainly two kinds of parts , include of zinc alloy die casting parts and plastic parts , These parts should be outsourced to do a good surface treatment. They may be coated by outsourcing factory, spraying oiled or electroplated. afterwards, These outsourced parts is be back to our factory, firstly, they arrived at our finished products installing and package department, our worker begin to check the appearance of these parts, and pick up some of imperfection and defective parts, sort them out in order.
Check the appearance of outsourced plastic parts
To check the appearance of outsourced plastic parts, a thorough visual and dimensional inspection is essential to ensure they meet both functional and aesthetic requirements. Here’s a step-by-step guide on how to conduct an effective appearance check.
1. Surface Finish
Verify if the surface finish (e.g., matte, glossy, or textured) matches the design specifications. The finish should be even across the part. Look for any inconsistencies in the texture or gloss. Uneven spots, streaks, or areas that look different could indicate issues during molding or finishing. Check for scratches, scuff marks, or any damage on the surface. These could occur during handling or shipping. Check for any dark spots or burn marks caused by overheating during the molding process. Look for flow marks or ripples, which are visible patterns created by the flow of molten plastic in the mold. Inspect the surface for any bubbles, voids, or air pockets trapped inside the part, especially in transparent or translucent plastic parts.
2. Color Consistency
Ensure the color of the plastic part is uniform across the entire surface, with no discoloration or color streaking. If the parts are produced in batches, compare parts across different batches to ensure there is no significant variation in color between them.
3. Dimensional Inspection
Check for warping or distortion, which can happen due to uneven cooling. Use a flat surface or measurement tools like calipers to ensure the part holds its intended shape. Measure key dimensions of the part using calipers, micrometers, or other appropriate measuring tools. Ensure the part is within the specified tolerances.
4. Packaging Inspection
Inspect the packaging to ensure that parts are properly protected during shipping and handling. Poor packaging can lead to surface damage or contamination, affecting the appearance.
5. Reference Samples
Here have a pre-approved sample or first article on hand to compare the appearance of new parts. This helps maintain consistency between production runs.
Check the appearance of outsourced zinc alloy casting parts
To check the appearance of outsourced parts, you can follow these steps to ensure they meet your quality standards:
1. Surface Finish
Inspect the surface for any blowholes, porosity, or shrinkage. These are common issues in casting and can affect both appearance and structural integrity. Ensure that the surface finish (whether matte, polished, or plated) is consistent across the part. The surface should not have any unexpected roughness or irregularities unless specified (for example, some parts may require textured surfaces). If the part has been electroplated, coated, or painted, check for uniform coverage. Ensure that no areas are thin, blistered, or peeling.For plated finishes like chrome, nickel, or zinc, the color should be consistent across the part.
2. Dimensions and Tolerances
Cast parts can sometimes warp during cooling. Use measurement tools like calipers to ensure the part’s shape is within the specified tolerances. Ensure the part’s dimensions match the drawing specifications. For critical dimensions, this may require precise measurement tools like coordinate measuring machines (CMM).
3. Finish Testing (If Required)
If the part has a specific surface treatment (e.g., powder coating, anodizing, or electroplating), you may need to perform tests like a thickness gauge test or adhesion test to verify that the finish meets technical specifications.
4. Packaging Inspection
Finally, check that the parts are packaged properly to avoid damage or scratching during transit, which could affect the surface finish.
Install zinc alloy parts into a finished product or functional part
Workers in finished products install and package dept are responsible for installing outsourced zinc alloy parts coated into a qualified finished product and functional part and packaging them and ready shipping them to our regular customers. Electroplated or oil-spraying die casting parts are all finished assembly and package here.
Assemble zinc alloy parts as one with screws
After zinc alloy die casting parts are deburred, they can be delivered to this dept for a testing install or install together and proceed the next procedure. Workers install these parts as one with screws respectively, then these assembled parts will be sent to our polishing production line. Its aim is to be more convenient to polishing the surface of these die casting parts so that electroplating these die casting parts better.
Install zinc alloy casting parts into a finished product
A finished product should be composed of a few metal parts and install them together and become a commodity, Then worker will pick up accordingly part and come with suitable another part and install these parts into a finished product. Sometimes, some parts is locked, they will repair and modify these parts until install them into a qualified finished product. At last put these finished products into the reasonable box and package vessel.
Install some functional parts or unfinished goods
Assemble zinc alloy part and plastic part into a finished product
Install zinc alloy casting parts and TPU mat and finish a car key cover
Assemble zinc alloy case electroplated from outsourced factory and our injected TPU mat into a finished metal car key cover, The metal car key cover is composed of two separated zinc alloy casting parts and a TUP mat together. Worker request install pick up one separated casting part from outsourced goods, and put suitable TPU mat into the casting part, screw the corresponding another part with screwdriver together and become a finished metal car key cover. Sometimes come with electroplated key hook in accordance with client requirements.
Install electronic , plastic and zinc alloy casting part
This a comprehensive dept, which responsible for all installment , assembly and package for parts and finished products. For a qualified electric product, which contain electronic components, plastic parts and metal cast part. So worker may install all parts into a reasonable product according to the guideline of client requirements, Afterwards, these electric products should be tested , ensure that they are qualified , packaging them and ready shipping. Just as our usb flash drive disk.
