Our Services

Mold Manufacturing

BL provides custom injection molds tailored for mass production.

Prior to mold fabrication, our engineers conduct mold‑flow analysis for parts to identify and prevent potential quality defects in advance.

Injection Molding Production

We are equipped with high‑performance Haitian and Toshiba injection molding machines, with clamping force ranging from 60 tons to 1600 tons.

Boasting advantages such as light weight, corrosion resistance, electrical insulation, easy molding, low cost, and flexible color & styling options, plastic components are widely applied across nearly all sectors, including consumer goods, industry, medical, military and infrastructure.

General‑Purpose Plastics:

Abbreviation	Full Name	Appearance & Texture	Core Advantages	Disadvantages	Typical Injection Molded Products
PE	Polyethylene	Milky translucent, waxy touch, good toughness	Low temperature resistance, waterproof & corrosion resistant, acid & alkali resistant, extremely low cost	Low hardness, easy to scratch, poor high temperature resistance (<80℃), hard to bond	Plastic bags, water buckets, bottle caps, pipes, turnover boxes
HDPE	High Density Polyethylene	Relatively rigid, matte finish	Better rigidity and hardness than LDPE	Slightly poor low-temperature toughness	Chemical drums, plastic basins, pipelines
LDPE	Low Density Polyethylene	Soft, easy to bend	Extremely flexible, tear-resistant	Low strength, easy to deform	Films, hoses, cling film, soft caps
PP	Polypropylene	Translucent, lightweight, turns white when bent	Lightest plastic, resistant to 100℃ boiling water, chemical resistant, foldable, high cost-effectiveness	Brittle at low temperatures, not UV-resistant, poor low-temperature toughness	Food containers, water cups, home appliance shells, automotive interiors, woven parts
PVC	Polyvinyl Chloride	Transparent or matte	Flame retardant, weather-resistant, low cost, easy to color	Releases harmful substances at high temperatures, additives required for processing, brittle at low temperatures	Drain pipes, profiles, wire sheaths, toys (environmentally modified PVC)
PS	Polystyrene	Highly transparent, hard & brittle, crisp tapping sound	High light transmittance, easy to color, extremely easy to mold, low cost	Extremely brittle, cracks under slight impact, not solvent-resistant	Disposable lunch boxes, transparent lamp covers, ornaments, home appliance liners
HIPS	High Impact Polystyrene	Milky opaque	Modified PS with greatly improved toughness	Loses transparency, average heat resistance	Refrigerator liners, toy shells, home appliance housings

Engineering Plastics:

Abbreviation	Full Name	Core Properties	Temperature Resistance	Advantages & Disadvantages	Application Scenarios
