Detailed Description
GP Mold provides full-lifecycle injection mold development and molding solutions for the global daily chemical, personal care, cosmetics, and household cleaning industries. We focus on meeting the mass production needs of functional and decorative packaging such as cream jars and bottles, pump dispensers, bottle caps, lipstick tubes, cosmetic cases, toothbrush handles, vacuum bottles, and measuring caps. We employ a closed-loop engineering development model, utilizing DFM (Design for Manufacturability) reviews, precision mold structure design, mold flow simulation analysis, cooling and ejection system optimization, and high-standard CNC/EDM/wire cutting manufacturing processes to ensure high-cycle production stability and micron-level fit reliability. GP Mold has the capability to support injection molding equipment from 100T to 1600T, and can provide both aluminum and high-grade steel mold solutions, adapting to production transitions from small-batch verification to tens of millions of units. This helps customers shorten verification cycles, reduce mold scaling risks, and improve overall yield, with specific optimization for the high aesthetic requirements and precision functional structures of daily chemical packaging..
Specifications
GP Mold's daily chemical packaging molds are designed with functional integration, aesthetic decoration, high consistency, and chemical stability as core design objectives. They support various advanced mold architectures, including hot runner, multi-cavity, stack molds, insert molding, two-color/multi-color overmolding, IML in-mold labeling, thin-wall transparent molding, and precision thread demolding. These are suitable for key components such as cream bottle bodies and caps, lotion pump/sprayer components (locking rings, spring seats, pistons, nozzles), lipstick tubes and lip gloss casings, cosmetic cases/powder compacts, toothbrush handles, flip-top/snap-on caps, vacuum bottle components, makeup brush handles, toothpaste tube shoulder caps, laundry detergent measuring caps, and triggers. Mold manufacturing tolerances are stably controlled within ±0.02–0.05mm, ensuring reliable critical assembly fits, uniform wall thickness, controllable weld line strength, precise molding of threads and buckles, and smooth demolding. We provide independent engineering and customized solutions for daily chemical packaging applications, optimizing exhaust systems and mold temperature control to ensure that part molding quality meets the stringent standards for cosmetic contact safety, high-end appearance, and functional durability,
Product Features
GP Mold prioritizes the use of high-hardness, corrosion-resistant, and high-polish steels in the manufacturing of molds for daily chemical packaging, such as S136, 718H, H13, NAK80, 420SS, and 1.2083. This is combined with controlled heat treatment (quenching/tempering/nitriding) and wear-resistant coatings (PVD/TiN/CrN) to ensure excellent dimensional stability and cavity surface integrity even under long-term high-temperature and high-pressure injection molding cycles. The molding material compatibility system covers general plastics (PP, HDPE, LDPE, LLDPE, PS, HIPS), engineering plastics (ABS, POM, PA, PC, PMMA, PETG), and high-performance daily chemical grade materials (transparent optical resins, pearlescent masterbatches, bio-based plastics, flame-retardant V0 grade, chemically resistant modified materials, and soft-touch TPE). Mold surface treatment strictly follows SPI/SPE standards (A-1/A-2 grade mirror high-gloss, B grade semi-gloss, C grade matte polishing), and supports VDI textures, laser etching, sandblasting, chrome plating, mirror polishing, anti-stick coatings, and IML in-mold labeling to ensure consistent high-end texture, matte, ceramic-like, or pearlescent surface appearance. We provide mold delivery and validation capabilities compliant with ISO 9001, FDA 21 CFR, EU 10/2011, and cosmetic contact regulations, and support cleanroom production environments (Class 7–8) and a traceable material batch management system.

Quality Assurance

GP Mold leverages high-precision machining centers and multi-dimensional inspection systems (CMM, 3D scanning, visual inspection, T1 mold trial data acquisition) to achieve consistent control over mold cavities, cores, precision threads, pump head piston mating surfaces, snap-fit ​​structures, thin-walled transparent areas, and parting lines. We have extensive processing experience with multi-cavity lipstick tubes, precision pump head components, mirrored cosmetic cases, and thin-walled vacuum bottle molds, ensuring stable mold tolerances, uniform wall thickness, and balanced melt filling. This prevents air bubbles, short shots, sink marks, warping, flow lines, and batch-to-batch appearance variations, significantly improving validation speed and mass production yield.

Customization Capabilities

GP Mold employs an "engineering one-case-per-project" mold development strategy, providing precisely customized mold solutions based on customer product design, brand aesthetics requirements, regulatory standards, usage scenarios, and production capacity needs. Our engineering team is involved from the initial design stage, providing DFM optimization suggestions, focusing on optimizing gating systems and venting designs for transparency, surface texture, and multi-material compatibility. We independently customize mold structure, mold temperature control circuits, cooling planning, ejection design, and surface treatment solutions, ensuring the mold has stable scalability during trial production and mass production.

Enhanced Durability

Enhanced Durability: The GP Mold mold material system and heat treatment solutions significantly improve the durability of molds in daily chemical packaging production scenarios. Through high-hardness, corrosion-resistant steel and advanced coating processes, the molds reliably withstand chemical additive residues, high-frequency opening and closing, and frequent color changes, reducing common failure risks such as cavity corrosion, wear, cracking, and deformation. This helps customers achieve longer mold life and lower overall maintenance costs.

Efficient Production:

We optimize molding cycles through CAE mold flow simulation (with particular attention to the optical performance of transparent parts and thin-wall filling), hot runner system design, efficient mold temperature control engineering, and precise cooling circuit optimization. This ensures that the molds have high-cycle production capabilities on the customer's injection molding platform. Through precise planning of gate location, venting system, and cooling system, we can shorten cooling time, improve part dimensional stability, reduce internal stress and scrap rate, thereby directly increasing customer productivity, lowering unit costs, and ensuring long-term mass production consistency.

Quality Assurance

GP Mold, based on the ISO 9001 certification system, implements strict quality control and data recording at every stage, from raw material incoming inspection and mold processing to assembly, precision finishing, T1 trial mold verification, and mass production. We conduct durability, filling, demolding, thermal stability, and full-dimensional functional verification of the molds to ensure they meet global standards for household goods and packaging products before formal delivery. We also support full-process traceability management of parts production and international logistics delivery capabilities.
