A buyer looking for a beauty instrument shell finds a page titled “Other products” and scrolls past, assuming the shop only makes random parts. That page is actually the shop’s platform statement: the same CNC hall, the same H13 slider inserts, the same 11-step deposit→R&D→sample→mass→after-sales workflow, and the same material rack (PA, PA6/6+GF, ABS, POM, PC, PP, PET, PVC, HDPE) serve beauty instrument shells, personal care product housings, power bank enclosures, Bluetooth headset cases, and medical device shells interchangeably. The “Other products” heading is not a miscellany bin; it is the catalogue entry for any precision electronic enclosure that does not fit the three named icons but follows the same tolerance regime—0.02 mm slider for IPX seal, 0.3 mm keeper for antenna window, 0.5% shrink compensation for ABS, 300,000–1,000,000 shot mould life, hot or cold runner chosen by material chemistry.

But why does a beauty instrument shell need the same 0.02 mm slider tolerance as a TWS earbud, how does the 11-step workflow replace cavity count as the real MOQ gate, and what makes a Guangdong/Shenzhen shop listing “other products” a platform partner rather a job-shop that says yes to everything and delivers nothing on time? Below is the full breakdown for beauty-brand product managers, personal-care device OEMs, power bank importers, and medical-enclosure specifiers evaluating a mould programme whose real spec is “three categories, one tolerance regime, one workflow,” not “we make anything.”

Why “other products” means a three-category platform, not a miscellaneous bin

The Other products — Precision Electronic Enclosures Plastic Injection Mould Beauty Instrument Personal Care Product Shell Power Bank Bluetooth Headset Medical Device Enclosure ABS PC PA PA6 6 GF POM PP PET PVC HDPE Hot Cold Runner Single Multi Cavity 300000 1000000 Shots UG PROE CAD CNC Milling Grinding OEM ODM Manufacturer Guangdong Shenzhen Szplastic-injection Mr Shan 86 13823654746 11 Step Workflow Contract Down Payment R&D Communication Scheme Confirmation Design Sampling Sample Confirm Mass Production Final Payment Inspection Shipment After Sales​ is anchored in five reconciled facts—category overlap in tolerance, surface-treatment anticipation, workflow-as-MOQ, material rack commonality, and the Guangdong CNC hall as the constant:
  • Beauty, Audio, And Medical Share The Same Tolerance Regime: 0.02 mm Slider, 0.3 mm Keeper, 0.5% Shrink.​ A beauty instrument shell (facial cleansing brush handle) needs a 0.02 mm seal groove for silicone cap IPX7, a 0.3 mm keeper for LED window alignment, and ABS shrink compensation at 0.5%—exactly the same three numbers as a TWS earbud case. A personal care product housing (electric toothbrush body) needs the same PA6/6+GF fibre-orientation gate placement as a medical device handle. The “other products” page is not listing random shapes; it is listing the same dimensional constraints applied to different silhouettes. The mould steel (P20/718H for cavity, H13 for slider), the runner choice (hot for PC/POM, cold for PA), and the surface finish (polish Ra 0.2 for medical, texture MT for beauty) are identical across the three categories. A buyer sending a beauty instrument enquiry gets the same fill-simulation report format as a Bluetooth headset buyer.
  • Surface Treatment Menu Is Mould-Anticipation, Not Post-Process Vendor List.​ The page lists “Surface treatment: As customer’s request” followed by polish, texture MT, paint, metallize, laser etch. That is not a vendor referral; it is a mould-design instruction. A beauty instrument that will receive a soft-touch paint needs a 0.2 mm paint-build allowance on the cavity dimension; a medical shell that will be laser etched needs a 0.1 mm step keeper for the laser jig. The mould is cut anticipating the painter, the metallizer, and the etcher—before the first shot. A shop that lists “surface treatment” as a menu item is telling the buyer: tell us your post-process now, not after T1, or we will cut the cavity to net shape and your paint will bridge the lettering.
  • 11-Step Workflow Replaces Cavity Count As The Real MOQ Gate.​ The sequence—contract → down payment → preliminary R&D communication → scheme confirmation → design and sampling → sample confirmation → mass production → final payment before shipment → inspection and shipment → shipment confirmation → after-sales follow-up—is why the effective minimum order is not “1 mould” but “deposit clears the R&D-talk slot.” A beauty brand with one SKU and a 3,000-unit forecast still pays the deposit, gets UG/PROE DFM, T1 in 4–7 weeks, sample confirm, then 3,000 units. The 11 steps are the MOQ: the deposit opens the engineering calendar. A shop that publishes all 11 steps on the product page is signalling that the R&D communication step is mandatory—no free DFM, no “send the file and we’ll quote tomorrow.” That filter separates committed OEMs from price shoppers.
  • Material Rack (PA/PA6+GF/ABS/POM/PC/PP/PET/PVC/HDPE) Is A Platform Inventory, Not A Capability List.​ These nine materials cover 95% of precision electronic enclosures: ABS for power bank cases (UL94 HB/V0), PC for transparent windows, PA6/6+GF for structural handles and hinge bosses, POM for gears and sliding mechanisms, PP for battery spacers, PET for insulation films, PVC for strain-relief boots. The shop stocks steel inserts calibrated to each material’s shrinkage (ABS 0.5%, PC 0.6%, PA6+GF 0.3% anisotropic, POM 2% crystalline) and maintains separate hot-runner profiles for amorphous (PC) vs crystalline (POM, PA) resins. A buyer asking for a material not on the list (e.g., TPU, LCP) triggers a new qualification cycle; a buyer picking from the list gets the standard 300k–1M shot guarantee.
  • Guangdong CNC/Milling/Grinding Hall Is The Constant Across All Three Categories.​ The same CNC 5-axis, the same milling centres, the same surface grinders that cut a Bluetooth headset mould this week cut a beauty instrument mould next week. The operator skill set (UG/PROE/CAM, electrode burning, EDM, CMM inspection) transfers across shapes because the tolerance regime does not change. A shop that advertises “Other products” is not claiming expertise in every industry; it is claiming expertise in one tolerance envelope (0.02–0.05 mm) that happens to fit beauty, audio, and medical enclosures equally. The “other” word is the buyer’s cue: send your 3D file, and the platform will tell you whether it fits the envelope before the deposit conversation.

Conclusion: “Other products” is the platform name for a three-category tolerance regime

The Other products — Precision Electronic Enclosures Plastic Injection Mould Beauty Instrument Personal Care Product Shell Power Bank Bluetooth Headset Medical Device Enclosure ABS PC PA PA6 6 GF POM PP PET PVC HDPE Hot Cold Runner Single Multi Cavity 300000 1000000 Shots UG PROE CAD CNC Milling Grinding OEM ODM Manufacturer Guangdong Shenzhen Szplastic-injection Mr Shan 86 13823654746 11 Step Workflow Contract Down Payment R&D Communication Scheme Confirmation Design Sampling Sample Confirm Mass Production Final Payment Inspection Shipment After Sales​ is not a miscellaneous bin; it is the catalogue entry for any precision enclosure that shares the same 0.02 mm slider tolerance, the same 0.3 mm keeper dimension, the same material rack (PA/PA6+GF/ABS/POM/PC/PP/PET/PVC/HDPE), the same hot/cold runner rule, and the same 11-step workflow that starts with a contract and ends with after-sales follow-up. Beauty instrument, personal care, power bank, Bluetooth headset, and medical device shells all converge on that tolerance regime because they all need IPX seal grooves, antenna keepers, fibre-orientation gate placement, and surface-treatment anticipation. Built on a Guangdong CNC/milling/grinding hall running UG/PROE/CAD, the platform processes all three categories through one DFM review, one steel batch order, and one shipment consolidation. Paired with a beauty brush handle and a TWS earbud case on the same PO, it becomes the multi-category anchor in a mould programme whose metric is “one tolerance regime, three categories, one workflow,” not “we make anything.”
