From Product Concept to Molded Mass Production
Custom plastic injection molding from our Zhongshan, China factory — established in 2012, serving 5,000+ customers across North America, South America and Europe. We mold drinkware, RV components and electronic products such as AC controllers, with in-house mold making, assembly and test. OEM from your drawings, ODM from a product idea.
Start Your Project
One Factory, Three Product Lines
Our Zhongshan factory has manufactured plastic and electronic products since 2012 — more than 5,000 customers served, with 70–80% of output exported. Three product lines share the same mold shop, injection molding lines and quality system.
Each line is backed by in-house structural design, tooling and mass production, so a custom plastic part moves from drawing to shipment without a hand-off.
-
Plastic Drinkware & Barware
Beer cups, tumblers, pitchers, shakers, shot glasses and ice buckets in PS, PC and Tritan — crystal-clear or colored, food-grade, with custom logo printing.
-
RV & Outdoor Components
Sewer hose supports, roof vent covers, fifth wheel lube plates and leveling blocks in UV- and weather-resistant PP, engineered for load and outdoor temperature.
-
Electronics & Smart Products
AC controllers, smart-home and appliance housings, interactive pet toys — ABS injection molding plus electronic assembly for finished devices.
From Concept to Molded Parts
Every project follows the same four stages — structural design and DFM first, then tooling, molding and assembly, with documented checkpoints between each stage.
Structural Design & DFM
Product structure, material selection (PS / PC / ABS / PP / Tritan) and manufacturability review before any steel is cut.
Mold Development
In-house injection mold making, trial molding (T1) and sample validation with dimensional tolerance confirmation.
Injection Molding
Parameter-monitored molding with in-process dimensional control for consistent parts at volume.
Assembly & Final QC
Assembly, functional testing and six-stage final inspection before packaging and shipment.
Materials, Customization and a Six-Stage Quality System
We mold in the resin that matches the application — and quality is integrated from raw material to final inspection, so every stage is documented and traceable.
Materials & Finishes
- PS — crystal-clear drinkware and barware
- PC — food-grade, high-clarity tumblers
- ABS — electronic housings and smart devices
- PP — UV- and weather-resistant RV parts
- Tritan — transparent, durable drinkware
- Custom colors, logo printing, surface finishing
Six Quality Checkpoints
- Incoming raw material inspection
- Mold precision verification
- In-process dimensional control
- Injection molding parameter monitoring
- Assembly and functional testing
- Final product inspection
Plastic Housings for Electronics — and the Boards Inside
Our smart HVAC control box program delivered three AC controller models for central air-conditioning systems — two-speed fan control, heating/cooling mode switching, temperature adjustment, timer and custom branding, in durable enclosed housings.
Because we also run in-house SMT & THT assembly and test, the plastic line and the electronics line work under one program: housing, board, assembly and functional verification — a finished device, not just a shell.

Frequently Asked Questions
Answers to the questions buyers ask most about our plastic injection molding and OEM/ODM service — what we mold, how projects start, MOQ and lead time, electronics inside the housing, and the quality system behind every batch.
What products can you injection mold?
Three product lines: plastic drinkware and barware (beer cups, tumblers, pitchers, cocktail shakers, shot glasses, ice buckets), RV and outdoor components (sewer hose supports, roof vent covers, fifth wheel lube plates, leveling blocks), and electronic products (AC controllers, smart-home and appliance housings, interactive pet toys).
We mold in PS, PC, ABS, PP and Tritan — transparent or colored, with custom logo printing. Typical capacities run from 25ml shot glasses to 4.3L beach bucket sets.
Do you offer OEM and ODM plastic manufacturing?
Yes. For OEM projects we manufacture strictly to your drawings, samples and specifications, ensuring accurate execution and stable mass production. For ODM projects our R&D team supports you from product concept and structural design through mold development, injection molding and final production.
The Zhongshan PHQH Manufacturing factory has run since 2012 and served more than 5,000 customers, with 70–80% of output exported to North America, South America and Europe.
What is the MOQ and lead time for custom plastic parts?
A typical MOQ is 3,000 pieces for standard drinkware and RV products, with 15–30 days production lead time after mold approval — for example a 20oz plastic cocktail shaker (MOQ 3,000, USD 0.50–0.75 per piece) or a 325ml food-grade PC whiskey tumbler (MOQ 3,000, about 20 days).
Mold and tooling lead time is confirmed per project after the DFM review, since it depends on part size, cavity count and material.
Can you build the electronics inside the plastic housing?
Yes. Our smart HVAC control box program developed three AC controller models for central air-conditioning systems — two-speed fan control, heating/cooling mode switching, temperature adjustment, timer on/off and custom branding.
Because we also run in-house PCBA assembly and test, the plastic line and the electronics line work under one program: housing, board, assembly and functional verification, from design through mass production.
Which quality checks do molded parts pass?
Six documented checkpoints: incoming raw material inspection, mold precision verification, in-process dimensional control, injection molding parameter monitoring, assembly and functional testing, and final product inspection.
For mold development we add mold structure verification before production, trial-mold testing with sample validation, dimensional tolerance confirmation and long-term mold maintenance, so stability holds across the full production run.
